Borders being primarily geography and culture is a very western perspective on things - in Africa for example a huge proportion of borders were arbitrarily drawn by colonisers. And even in Europe and other western regions, certain borders are the way they are more for political reasons than because of true distinctiveness. Also, different regions within countries tend to be able to maintain their distinctiveness rather well despite a lack of internal borders, and in parts of Asia and Africa were borders were recently enforced by external intervention, culture continues to exist across them and despite them, so it feels like cultural differences and borders are not as closely correlated on a global scale as one may at first think.
