It's not even really about magical power. Within the world, it's about political power, and the fact that the alicorns are royalty. In reality, it's about the nature of the fanfiction. Much of the fanfiction is about the discussion and debate between the four princesses of Equestria. Therefore, any pony that isn't an alicorn tends to fade into the background a bit, taking the role of a driving force on the main characters. The main power that the alicorns have is the literary device of being major characters.
I spent two minutes arguing about why Discord was a stupid example, but then realised Discord is actually good now. Discord doesn't really stylistically fit into any of those five arguments, however. Looking at him, I imagine he would abstain from the issue. I simply don't see why he would care, period. The only thing he might do would be to try and get Fluttershy immortality, but even if he did take on that side, I don't see him entering the political arena. Adding an OC immortal isn't really something I want to do. For one, I suck at making characters, and for another, the thing I enjoy most about fanfiction is exploring the world that already exists.
The political opponents are really more of an obstacle than a character. In my opinion, they would be far better off as an abstraction: Instead of the Griffon Prince coming to Equestria to argue with the princesses, the argument is "The griffons won't be happy if we do this, and there could be consequences."
As for Twilight and Cadence, just because Twilight's bookish doesn't mean she doesn't care. I assume she'd be on the forefront of research to solve mass-transformation-related problems, but to do that, it's only logical that she convince the other princesses they should actually go ahead and agree to the transforming first. I agree that Cadence actually would be a likely candidate to take on the mantle of "We should transform everypony as fast as possible" but that argument is likely to be pretty soundly defeated in the first few chapters anyway. Thus, it's better for the fic if Cadence has a pro-alicorn, but reasonably well thought out view. It's okay for Twilight to hold that view for a while and still be rational, because it's a snap judgement: She only finds out that Cadence and herself are immortal when she actually gets transformed. Before Celestia mentions it, Twilight assumes that only Celestia and Luna are immortal.
Essentially, it would make sense for Cadence to be an irrational character, but I think the fic is overall better to give Cadence a slightly different character and allow her to be more rational, and thus increase the amount of solid discourse within the story. It's a sacrifice, but I think it's one worth making. I actually think the irrational view is more in Cadence's character, but the alicorns are already being bumped up in rationality to begin with: One more won't be too odd. And a rationalist!Cadence would likely take on the role of "Do it once we're sure it will work." I actually have a scene I drafted out which has this particular argument in it, which I'll send to you as an example of Cadence's character. (I don't want to make my comments TOO long in length, we already have a massive comment chain as it is!)
EDIT: I am now taking arguments for alicornism. Alicornism being the placeholder term I've given to the stance that all ponies should be alicorns. Please PM me or post here if you have a good one, or an argument against one of anti-alicornism's strongest points: Overpopulation/over-use of resources, magical abuse/existential risk, or upheaval of the respect ponies have for their rulers due to their alicorn status. I would prefer general arguments for alicornism over counter-arguments if possible. Deathist / anti-alicornist arguments are still fine to post here.
Disclaimer: I'm not sure if this is worthy of a discussion post, but I figured, given the amount of people on LW who like My Little Pony, it would have at least as many potentially interested people as a regional meet-up thread would, so I figured I'd give it a shot. If this is too trivial or frivolous for LW, feel free to tell me and/or downvote, and I'll refrain from such threads in future. A place where I could go to find some help instead of the Discussion section would also be greatly appreciated in such a case.
So I had an idea for a one-shot or small novella, depending on how the plot developed, about an argument between Twilight and Celestia. Twilight finds out she's immortal now that she's an alicorn, and Twilight then decides that, given the standard anti-death concepts that immortality is good, death is bad, and so on, they should turn everyone who wants to be an alicorn into one.
The problem is, I'm having a very difficult time coming up with actual arguments for Celestia.
- Celestia herself is immortal, she's lived for well over a thousand years, and she isn't horrifically depressed, so clearly, immortal life is worth living and there's enough stuff to do with an extended lifespan.
- For the purposes of this fic, it's possible to turn anypony into an alicorn. I'm likely going to go with the idea that the spell can only be used a few times a year, but that's still enough to turn anyone who wants it into an alicorn within a couple of decades via exponentiation: The first targets can all be gifted unicorns who can be easily trained to use the magic.
- In most of the "Immortality sucks" fics I've read, the only real argument that immortality sucks is that you have to watch everyone else grow up and die. If a large majority of the population were turned alicorn, this wouldn't be a problem anymore.
- Nothing in canon suggests that there's any sort of religion in Equestria. Even in fanfics I've read, I've only read one fanfic where someone made up an afterlife that some ponies believed in, and in many more that I've read, Celestia's name is actually used in place of God in various sentences, like "Oh for Celestia's sake!" Thus, it's unlikely they'd believe in an afterlife: Both in canon and the majority of fanon, the closest thing to a God appears to be Celestia herself.
I've come up with arguments for Celestia by roleplaying the argument out by myself, but I haven't come up with anything that Twilight can't just shoot down, and I'd prefer if the argument wasn't just Celestia getting steamrolled, and I'd like to do this by strengthening Celestia's side, not weakening Twilight's.
Is the argument for deathism really that weak? I've read over the Harry vs. Dumbledore deathism argument in HPMOR several times looking for ideas, and IIRC Eliezer actually claimed he steel-manned Dumbledore's position, but I don't find anything Dumbledore says convincing in the slightest, and ended that chapter feeling that Harry was the clear winner in that debate, and that's with Dumbledore having access to arguments that Celestia doesn't, given that in the Potterverse, nobody actually knows what it's like to be immortal, and Dumbledore believes in an afterlife.
Some other arguments I've come up with for Celestia:
Argument: We can't just have a massive ruling class.
Response: There's no need for alicorns to be royalty. "Princess = Alicorn, Alicorn = Princess" is only something that law and tradition dictate: They can be changed. After all, Blueblood is a prince and not an alicorn, and it's certainly possible for an alicorn to NOT be royalty, if the princesses wanted.
Argument: Harder to keep the populace in line, if everyone has more power.
Response: Celestia's not exactly going around fighting criminals herself with her alicorn powers, so Celestia being much more powerful than others isn't necessary to keep the peace. If anything, an alicornified populace is MORE likely to be able to govern itself: Atm, a pegasus criminal can only be pursued effectively by about one-third of police officers, for example.
Argument: Overpopulation.
Response: One response to this is the idea that, starting a year or so from a royal edict, ponies who wish to be changed into alicorns aren't permitted to give birth more than once or twice. A broader response is that "overpopulation" isn't actually a reason to oppose alicornification, it's just a problem that has to be solved in order to do it. Saying "There'd be overpopulation" and then forgetting about the entire idea would be like Twilight saying that they didn't know how she was supposed to save the Crystal Empire from being banished again when she got given the task, and responding to this by saying "Oh well, guess that's it, we may as well pack up and go home." rather than trying to actually solve the problem. That said, this is the only truly legitimate argument I've come up with, an argument that requires real thought to fully defeat, rather than an argument that has an easy response leap to my mind.
Argument: Mortals wouldn't understand the consequence of their decision.
Response: Again, several arguments for this. Firstly, there's no reason to believe the alicorn transformation is irreversible, even if it's not currently known how to transform it back. Secondly, Celestia can already predict the consequences, and since she thinks HER life is worth living, clearly there's a solid chance that other ponies will have their lives worth living as well.
So, the questions to ask:
Are there good arguments for Celestia I haven't thought of?
Are the arguments I've already posited sufficient to not straw-man the lifeism position, and to allow for a reasonable argument?
