@MillennialWoes: Suggested expansion: the only value of diversity(Heterogeneity)

@MillennialWoes: Suggested expansion: the only value of diversity(Heterogeneity) is in markets because it creates the greatest variety of customers and the greatest variety of solutions for them, with the lowest opportunity cost, and the greatest low price competition.
The greatest value of homogeneity is in familial, social, political, and territorial organization, which eliminates the greatest number of differences, and the greatest degree of competition in the pursuit of mutually desirable commons that provide lower costs, higher trust, higher velocity of cooperation, and higher willingness for caretaking and competition for all.
The best for all is:
Large Heterogeneous markets(Trade, Consumption)
and
Small Homogeneous Polities (Investment, Commons).
