It sounds like you could be a voluntaryist. A society with no coercion, we could try different systems and find a best one, or maybe there is no best one. If you like tax funded healthcare and police and schools (even though it's proven that these services are far better when privatized) then you could get together like minded and do that. No one stopping voluntary interactions. As opposed to your idea where you have to ask a government to let you live how you want.
