Well, if we are talking about a city, space is often somewhat scarce. Regardless, I don't think that would reduce segregation. I think the biggest limitation is "unhappy" polygons moving to random locations, instead of having some choice in the matter. Reducing this limitation would result in faster convergence towards a stable, segregated state, as the choices made would reflect the bias of the participants.
