> National borders are very real to most nations. Similarly, someone's specific plot of real estate feels very real to them as well The borders of plots of land are frequently disputed. There are plenty of places in the US where two or more deeds define overlapping properties (which should obviously never be the case, but here we are!). Country borders are no different, and it's unsurprising that they very frequently disagree. The US and Canada have disputed territory, even. To suggest that borders are "real" in any sense implies that there's one correct, canonical set of boundaries. But there's not and never has been. There's no singular authority that decides what the borders should be. Wars are literally being fought right now over borders.
