I really do like dxu's "If you harm me greatly, the universe will end" or something similar in Parseltounge, though. (Since it will end with or without Harry's intervention, this is still true.) It seems the most elegant solution and would buy time to implement some other solution. hm. This system ate my previous post.

I'll have to rewrite it.

While this might be a little deus ex machina for Eliezer Yudkowsky, Harry can create a doppleganger of himself. He's recently learned more complex transfigurations. Dumbledore had access to the Philosopher's Stone, which could make such transfigurations permanent. Harry's special patronus seems to help the process in some cases. These are very complementary abilities.

If Harry could clone a copy of himself from a part of himself, and that copy could be made to forget it's origin then the captured Harry might not have to be the real Harry at all, and could be sacrificed. Harry could theoretically make an army of himself, even, and hide them in his bag of holding or some other place like a clown car. Further, Harry could clone himself and use that clone to make a horcrux gaining some kind of immortality without murder. I doubt that Dumbeldore would allow such dark magics, though.

Here's my idea, which I've posted as a review on FF.net. Harry has advanced transfiguration. The Philosopher's Stone can make transfiguration permanent. Harry can bring life to dead things. This is very close to Harry being able to create copies of himself, which would surely be attractive to Harry. The question, then, is; when did Harry first realize this capacity?The possibility of creating a body double might very well have been enough to have persuaded Dumbledore to let Harry use the Philosopher's stone, which he seems to have access to. Or Harry might have procured the stone himself, which he seems able to, intellectually. It's just a matter of procuring a confundus charm. The current Harry could have been memory-charmed into believing he was the original Harry and this ruse may have gone on for quite some time (though reviving Hermione would have made it obvious that he had this power, and I'm not sure if Harry would have demured to do so if he thought he could. I suspect he'd have to be persuaded by someone else.) It might help in explaining why Harry could attack Voldemort, since Voldemort's curse bound only Tom Riddles "descended from him", and the current double would have been "descended" from Harry.

In this case our Harry could be destroyed and another Harry would still live (and could even play off his surviving destruction as a type of magic, snapping his fingers.) Similarly, could Harry sacrifice one of his doubles to create a horcrux and then inhabit a spare transfigured body, laying in stasis somewhere (like his bag of holding?) This seems a bit dark for Harry, but maybe possible.

I'm not sure what the limitations on this type of duplication magic would be. Perhaps multiple Harrys would need to be created 'from hit points' and even if one Harry could make another they might each be weaker or draw on the original Harry's HPs. But an army of Harry Potters striding over the hill wouldn't be a bad solution to this problem. Chaos Army of One. etc.

"We should put more trust in larger scale organizations who are doing exploring, like GiveWell, and pool our resources."

I wonder about the notion of scalability, because with any information provider there's the possible issue of corruption. Is it better to have a large organization which is easy to track? (Goodwill and the Red Cross seem to give their CEOs pretty high salaries, considering that they're charities.) Or is it better to have a system which is more robust to corruption and tunnel vision due to multiple redundancies? Do larger organizations attract a certain type of social climber? I have no doubt that there are economies of scale. Part of the reason I'm asking these questions is that corruption seems to be a universal human stumbling block, and one that is often inadequately addressed. We project generously and assume that the heads of organizations are "basically like us" and altruistic in their intent. Neither is probably true, as the upper ranks of large organizations tend to collect those who are particularly attracted to climbing the ranks.

Simplest; The goblins, and wizard society just do not approve of outright theft, even from muggles, and there are magics that will reliably mark stolen goods. So if you want to come up with gold by the tonne, you need to either actually engage muggles in trade (eewww) or go hunting for treasure with no (living) owners.

More amusingly: I am not at all sure competent wizards have much need to care about coin at all. Lucius is a political creature, so he needs ways to bribe idiots, but a wizard that keeps their newt skills up to scratch is pretty much carrying around a cornucopia machine in their pocket. Sure, you could spend a bunch of effort and rob a bank, then use that gold to have a house built.. Or, you know, save yourself the hassle and raise a cute little tower from the bones of the earth/bend space and live like a king in a post office box.. ect.
