If the long term goal is to sell items directly there is plenty of room for margins. Combined with Google Now, you should rarely ever run out of anything you need. I like thinking about how an urban environment re-arranges itself when you remove the need for most store fronts, and driving. ATMs, CVS/Walgreens/Duane Reade, Target, Best Buy; these are all places that probably won't exist in the volume they do today in eight years. Whether it was low interest rates or other factors that made them multiply, it won't really matter. A mobile phone + a neighborhood distribution center should be all that is needed. Automating checkout won't be enough. (In an ATMs case, cash just won't be used except may be for narcotics.) What happens to Starbucks, McDonald's, and other chain food service is a whole other question.
