well yeah, war is a human constant, there is no fixed way to dispute arbitrary claims such as "land rights" and "dibs" on ownership of things outside of war. I mean sure there's legal agreements, but if you don't agree, it's null and void, now nothing matters anymore. I guess you could simply play rock paper scissors for dibs but i don't imagine that's going to be very popular.

This is even a constant within evolutionary biology and the animal kingdom at large. Modern predators are only so deadly because it was advantageous to reproduction.
