Isn’t “the state” just cultural mechanisms extended beyond familial or interpersonal ties? There’s a threshold where the group becomes too numerous for a member to form social ties with all other members. At that stage, culture becomes a force unto itself, propagating further than the members that comprise it. That point, more than money, seems to be where exploitative behavior becomes more likely to take hold.

Like, feudal aristocracies were plenty exploitative, plenty domineering. But they didn’t necessarily need money for it; a lot of them operated on barter economies. They just needed a knife-point and a cultural belief to justify the domination. Money is just an innovation on a much older process.
