As for your point 1, I'd like to clarify that you only have the right to swing a stick around on your own property, or on that of someone who'll let you. Also aggression isn't the same thing as hurting people, since it includes things like trespassing.
I'm a quasi-anarcho-capitalist. I believe in abolishing the state and replacing it with small voluntary non-state-minarchies. Not sure where I was going with this.
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.
