You write as though the amount of free land or buffer zone was constant, that is, as though the world population was constant. My point t was that walking in separate directions was a more viable option when the population was much lower...that, where available, it is usually an attractive option because it is like cost. That’s a probabilistic argument. The point is probabilistic. There have always been wars, the question is how many.
Do I really have to explain why Australia wasn’t a buffer zone between European nations? On a planet, there is no guarantee that rival nations won’t be cheek by jowl, but galactic civilisations are guaranteed to be separated by interstellar space. Given reasonable assumptions about the scarcity of intelligent life, and the light barrier, the situation is much better than it ever was on earth.
