Meta-Preferences and Market Incompletability

This establishes that meta-preferences combined with comparability lead to paradox…

Whereas the 4 links here are threads summarizing my view that meta-preferences are linked to altruism:

Put those facts together and you get that our economic system, by avoiding paradox, has made it unnatural to express altruism… very roughly…

I feel like this identifies a problem to which the solution is not obvious…
