Why do you assume they do? It isn’t true that “everyone” insists upon it. A minority are quite capable of holding a country by force. In fact, that’s pretty much the definition. Making it appear to be some Universal Truth which people can’t even vote upon merely helps make it easier to put over on people.
One way is that social constructs tend to require people to subscribe to or believe in them. A more useful distinction is whether one is imprisoned within a system run by and for some people or parties one doesn’t even know - or if supposedly free people can implement their own systems without interference. After all, as good capitalists, people would want to see competition and see which of the many local systems had the most to offer. /s
I didn’t mean that kind of “passing”…
Anyway, I forked all of this to another topic, so as to not derail this one.
