The air pollution problem that commuting causes may be negated in the future with increases of working from home. I don't see how energy is significantly cheaper in the city vs. in suburbs or rural areas, aside from transmission costs. To which economies of scale do you refer, and how would cities become more comfortable? I assume maybe you mean cheaper? Housing costs, for instance, aren't actually lower, people just live in disgustingly small spaces. I think you're mistaken about the inclinations of the average person. People like having a decent amount of living space. I don't think most would want to give up a back yard.
