You don't include cultures in CEV, you filter people through extrapolation of their volition. Even if culture makes value different, "mutilating women" is not a kind of thing that gets through, and so is a broken prototype example for drawing attention to.

In any case, my argument in the above comment was that value should be given (theoretically, if everyone understands the deal and relevant game theory, etc., etc.; realistically, such a deal must be simplified; you may even get away with cheating) according to provided assistance, not according to compatibility of value. If poor compatibility of value prevents from giving assistance, this is an effect of value completely unrelated to post-FAI compatibility, and given that assistance can be given with money, the effect itself doesn't seem real either. You may well exclude people of Myanmar, because they are poor and can't affect your success, but not people of a generous/demanding genocidal cult, for an irrelevant reason that they are evil. Game theory is cynical.
