There are still a lot of underlying assumptions here worth noting though. You're assuming we must have a government and what it must be able to do, like charge me taxes or gatekeep certain activities behind licensing systems.
I'm not arguing we don't need a government. But to silently take for granted that everything from income taxes to public roads and travel restrictions are a given jumps ahead here.
We could decide, for example, that the government shouldn't be allowed to centralize certain data and remove some of what we expect them to do instead.
