Don't read too much into it, economic models like this are wrong in the same way the original version of Einstein's theory of general relativity fails to model 90% of the stuff in the universe, except that in this case it's more like 99.9%. The original paper[1] describes a spacial equability models where selfish agent move to maximise some utility function. It's in the vein of Shelling's segregation model. It's the sort of idea that the non-cognitive repeat ad nauseam. [1] https://www.princeton.edu/~erossi/CHSR.pdf https://www.princeton.edu/~erossi/CHSR.pdf
