the space problem is a bit different. we probably don't want to turn the whole planet into high density housing, even if we could energy wise, but the only thing getting in the way of solving the problems we have is politics as in unwillingness to cooperate for the greater benefit of the world instead of for selfish reasons. People don't have a good grasp on the space issue because they hadn't play with the math, or investigated our terribly inefficient and often ugly land usage pattern. When I think of space, I think about acrologies, hardly high density dystopian hellscape. We would realistically construct them over time in module instead of trying to do monolithic designs that I often see proposed.
