So now flying a kite...
... or even jumping a bit too high and a bit too long should fall under FAA rules? Pole vault athletes should ask for a take off clearance before jumping?
Anyway, flying drones over inhabited areas (and roads) should needs some kind of regulation - there are safety and privacy issues to take into account.
