Sure. Push and pull. The point is that needs effort to work at larger scales. We don’t “naturally” organize into nations of three hundred million or a billion. To the extent we do, we also “naturally” go to war.
There is a pretty interesting study of a large group of chimps. I dont remember where exactly but they have been civil warring the last 15 years or so. Point is, it seems that there is some kind of innate group formation process.
