Like, the only reason countries exist is because some rich guys decided that they ruled this chunk of land, and everyone else just kinda said “Yeah, whatever, I don’t really give a shit, just let me farm and leave me the fuck alone”.
Then the rich guy on the next bit of land said “I want a bit of what he’s got going on”, and before we knew it, all the bits of land were ruled by people who’s only claim to them was that they were the first to have the idea.
Fast forward a few thousand years, and some of the bits of land are ruled by people who wear gold hats and spout a load of bollocks about divine right, while some of the bits of land are ruled by people who convinced the rest of the people to let them do it, and really, there’s no difference between, like, France and Spain, but some old dudes drew a line and said “Nah, that bit speaks this version of a language, and that bit speaks another version of it”.
You ever think about that?
Sometimes borders represent the differences between groups of people and what they find important on a range of issues including trade, security, and how they choose to govern themselves. (When those people aren’t being forsably ruled.)
