That's a great question, and my trivial answer is: Because people want to sleep in a different place from where they spend the day. Now, is it good for us, abstracting out travel time, for those to be in very different places? That's a whole other issue. I do imagine communities will see many of the same benefits as individuals; that is, lower transport costs will mean its possible to build affordable, self-contained communities farther away from urban centers without sacrificing quality of life (including the ability to go to the city if you want to). But that's behind the event horizon to me; hard to speculate.
