As more people in outlying areas start to work from home electronically, and if they can get goods delivered by low energy drones, that would lessen some of the cost of sprawl. It would still be an inefficient way to live, in terms of utilities and social services like police response times, fire departments, etc. but less harmful than it is now if it hugely reduces single car long distance commuting.
