There are a lot of legal issues concerning the use of unmanned drones. Besides, this game is intended to be less for the sedentary and more for the active. So I don't mind marching out to claim stuff around my home town. The only issue is how long it takes to harvest using the single virtual drone in our network. If multiple drones with higher top speeds or greater carrying capacity could be included, that would speed along resource production (doesn't have to be right away though).
And of course, the ability to scroll out to a wider range (say, 5-10 square kilometers) would lessen the pain of having to locate local 'hotspots' of resources.
