Crowding people into buildings has never been natural and therefore no policy or economic incentive can change that. Certain jobs require hands-on work, but unless you are physically working on something (human, car, machine part, etc) there is zero reason for you to be in a building with other people other than for the ego satisfaction of yourself or others. The "economy" is not a physical thing - it's purely an abstract of trade. Modern trade is working just fine with modern advancements in communication, transportation, material sciences, physics, robotics, and other areas. Those of us working on things simply evolve to the next level and become supervisors or achieve higher levels of technical proficiency. We also tune-up our home lives to reduce any unnecessary spending. This puts the real, hard-value American economy light-years ahead of the one which now only exists in theory, as it doesn't transfer to our current world from a purely mathematical sense - it just doesn't line up. Success in today's economy is a fair game driven by delivery of value, and there will be a clear line drawn between those who produce value and those who seek gain from the production of value by others.
