No need for ad hominems, let your arguments speak.
> like small population or they are "backwards" subsistence farmers is irrelevant to the fact that civil order was maintained by polycentric law for 3 centuries.
Both subsistence farming (e.g. means of production that are by definition not exhibiting division of labor) and an extremly low population density mean that both communication and coordination between people are orders of magnitude smaller than in complex and dense societies. That's pretty much consensus both in macro economics and in sociology.

I'm an empirical scientist, so not exactly opposed to experimentation. Has it occured to you that "my type" simply isn't persuaded by your argument?
