First of all, I think it is a reasonable assumption that there are only finitely many people in the universe, in which case the order does not matter.
Also, of course the location of people matter. If you move all earth people at this moment to mars, we will all suffer and die. In the same way, say there 100 other galaxies in which there is another earth. Move all of these people here, and we will have an enormous over population.
