What you see as the factors holding back people from cooperating with modern analogues of FAI projects? Do you think those modern analogues could derive improved cooperation through broadcasting specific enfranchisement policy?
As a practical matter, it looks to me like the majority of wealthy, intelligent, rational modern folks an FAI project might want to cooperate with lean towards egalitarianism and humanism, not blues versus greens type sectarianism.
If you don't think someone has enough political clout to bother with, they'll be incentivized to prove you wrong. Even if you're right most of the time, you'll be giving yourself trouble.
I agree that very young humans are a potential difficult gray area. One possible solution is to simulate their growth into adults before computing their CEV. Presumably the age at which their growth should be simulated up to is not as controversial as who should be included.
Sorry, you've lost me. Can you clarify what the different arguments you refer to here are, and why the difference between them matters in this context?
FAI team trustworthiness is a different subject than optimal enfranchisement structure.

I'm not sure what those modern analogues are, but in general here are a few factors I see preventing people from cooperating on projects where both mutual cooperation and unilateral cooperation would be beneficial:
This is for anyone in the LessWrong community who has made at least some effort to read the sequences and follow along, but is still confused on some point, and is perhaps feeling a bit embarrassed. Here, newbies and not-so-newbies are free to ask very basic but still relevant questions with the understanding that the answers are probably somewhere in the sequences. Similarly, LessWrong tends to presume a rather high threshold for understanding science and technology. Relevant questions in those areas are welcome as well. Anyone who chooses to respond should respectfully guide the questioner to a helpful resource, and questioners should be appropriately grateful. Good faith should be presumed on both sides, unless and until it is shown to be absent. If a questioner is not sure whether a question is relevant, ask it, and also ask if it's relevant.
