I'm not really convinced of this in the long term. Commodities like baskets or vases were something that were once made by each tribe individually but became industrial products made in relatively fewer places (relative to human settlement) at much larger scales.

The economies of scale of cloud computing seem to prescribe the same trajectory to computer services as well for completely material reasons, not ideological ones.

In any case, differentiation is only made possible by a base of de-differentiated socialized production. Electricity.
