Ah, thanks, that's fair since most people are going to make those sort of voluntarist associations. I guess I was imagining an edge case for people who opt to not do that, but that feels an awful lot like when people today make arguments like "well, nobody's forcing you to carry a phone!"
I suppose this all comes back to the point that nobody is pragmatically advocating for absolute anarchy - it's simply a valuable concept to reference as we collaborate to build actual, functioning social systems. Or, at least, that's how I tend to think about it ¯\_(ツ)_/¯
