This is what happens whenever I debate "libertarians". I mention overarching tendencies, only to get replies about fine logic minutiae. I'm guessing obsession with details, and blindness to the big picture is also a trait of Ayn Rand fans.

Indeed. I'd even argue that France doesn't actually exist. People exist. The Earth exists. Objects exist. But "France" is just a concept and a set of traditions that a (rather large) number of people choose to talk about and believe in. But it has no independent existance. You cannot see France from space. If everyone's minds were wiped tonight and then we woke up tomorrow and got out of bed it would be as if France didn't exist. Beds would still exist. Food would still exist, our bodies, buildings, vehicles, etc.

Also the idea that only nation states are sovereign could be argued to be a combination of a benign constructive social conceit AND also a cognitive tool designed by elites to control the masses. Both of these things can be true at the same time. I'm not arguing that anarchy is a good thing. But something like it IS the natural state of affairs, physically speaking. And the only reason people tend to prefer something other than anarchy is when they see the relative benefits. But the alternatives to anarchy (families, tribes, cities, nations) are things we choose to do, we choose to engage in, and choose to go along with. Just as millions and perhaps billions of people choose to go along with the idea that France exists and is a sovereign entity. But let's never forget this is only true to the extent that enough (of the right) people want it to be true. And that can change.
