That we need markets so that we can cooperate on means if not ends, and that we need markets for commons so we can produce commons necessary for the differences in our distributions is hard to argue with.

The question is whether we need variation in the law by which we reconcile disputes, and whether we need variation in truth vs falsehoods. While it is possible to speak truthfully in most modern languages with some effort, it is not clear that cooperation is possible between the more truthful and higher trust polity, and the less truthful and lower trust polity. Or between polities that are both low trust and both high in falsehoods but that are incompatible because those differences are irreconcilable.

All humans can cooperate perfectly under aristotelian (testimonial) truth, perfect reciprocity, and markets of voluntary cooperation. But this means that those of the best genetic ability will eventually replace those that are less so. So there is group evolutionary advantage to hostility, differences, uncooperativeness, falsehood, and deceits.
