Personal airplanes already exists, that does not mean people fly around and hit buildings or shoot people. There are aviation regulations in place and airspace is heavily regulated. I don't think drones will be any different regardless their size. If a tiny drone can fly miles in any direction for hours it could be banned outdoors or limited to certain areas.
