That's not at all the problem.

What about navigating TFRs? Class B airspace? What about failures of the rotors whilst flying over heavily populated areas? Will these things be equipped with TCAS to avoid oncoming traffic? What happens if the path-finding algorithm to get from Amazon's warehouse to your house goes batshit insane and flies it in the approach path to LAX? Who files the flight plan for each of these things?

Not to mention UFOs. And as someone said, the drones would make archery a very popular sport again. ;)
