That again disregards the fact that those regimes have to be sustained economically.

See, no matter what people believe, which gods they pray for, what ideologies they follow and how they manage their lives, they inevitably increase the means of production. Even if a given person is dumb and useless, that person would still prefer cheaper goods to more expensive ones, therefore generating economic signals for investments in production improvements.

Increased means of production mean lower transaction costs. Lower transaction costs generate decentralization. Decentralization progressively make centralized regimes not viable.
