I used it as a metaphor and not as an example.
I advocate state as a service within anarcho-capitalism. Think of it like smart contracts built on Ethereum, EOS, NEO or an Operating System. Naturally this would create a bunch of city states and confederates that would function as minarchies. Theoratically it's possible that people would opt in for an one world minarchy but the chances of that happening are pretty close to zero.
Great to meet a fellow quasi-anarcho-capitalist.
