They will not ban them for hobby use but they will draw the line for commercial use and require some kind of licensing or regulations.
Otherwise, if you know the folks like I do, every damn one of them will trying to make money with their toys in order to pay for their hobby. The FAA controls the airspace over the US from ground level to ???? way up yonder and they are not about to let 50,000 drones wonder around with no control whatsoever. All it is going to take is for one of these idiots to have a fatal collision with an aircraft for their fun world to come to a screeching halt. It almost happened awhile back right over NYC when a couple a airliners nearly hit one with a reported 8’ wingspan.
One of these idiots was out with his drone taking pictures of the 3800 acre fire 2 miles east of me last weekend...at the same time 10 helicopters and a DC-10 air tanker and several other air tankers were trying to keep people's houses from burning.
It's just a matter of time before some little Herkimer takes his toy drone out for a spin in the subdivision built at the end of the runway 25 years after the airport was built and takes out an engine on a 767 at takeoff.
