Hold up, I thought we were talking about the state running things? Of course everything has a central authority; this includes unions, churches, and corporations. Though, we certainly don’t need the state for a black market to run its business. However, I guess it wouldn’t really be a black market if there wasn’t a state to declare things illegal 🤔.
I absolutely agree with your second half though. The black market is a perfect capitalist example, and I believe it is an inevitable response to state authoritarianism.
