> a reasonable vision of the world based on everyone's moralities

I was actually careful not to say "moralities" as parameters of the model, because people's claimed moralities are often really awful representations of what they actually want, believe, or care about in life. Nobody is against abortion when their own daughter gets impregnated by a rapist or when it's their own ectopic pregnancy. Abortion is only controversial because it's politically convenient. It's not actually a particularly difficult moral conundrum, which -- again -- you can tell by the fact that everyone is pro-abortion when it's them or their daughter. I don't care about people's stated morality. I care about what actually brings about happiness vs. suffering.
