It’s all borders. They’re nonsense, other than physical separation by water or mountains being a thing, arbitrary political lines have always been nonsense.

It used to not even be like this - you could just like; move to France 150 years ago or move to the US and nobody gave a damn (I’m simplifying it, but basically this is the case). The only places where this wasn’t the case was like messed up countries like Russia or feudal China, but even then, borders were way more porous.

We got stupid after WW1 and were paying for that to this day. These imaginary lines will go away one day, I just hope it happens before their cause our extinction.
