You honestly think that quitting Facebook is harder than changing countries? Opting out from your country is currently near impossible for most people, and the only reason it is possible for the few who can is globalism. The place where moving between countries is the easiest is the E.U. and that's precisely because of the supra-national structure.

I am not a centralist when it comes to the official international institutions precisely because the no opt-out you describe (which is true for official institutions, not so much for Facebook). But at the same time, without international cooperation and with "every nation for itself" we end up much worse off at a personal and species level.

Quitting Facebook doesn't effectively prevent it from affecting you and your social network.

And not living in many countries certainly does not prevent them from affecting you. The world is deeply interconnected no matter how you structure it, from nuclear proliferation to pollution. You are also not immune from states you opt out of, if you even manage that.

Not that shadow profiles are a good thing, though. But I think this is drifting from the original topic, Facebook is, as of now, eminently more "escapable" than most nation states are. Certainly than any of the great powers, even if you don't live anywhere close to them.
