I'll take this off the deep end. A couple Canadian geese (average weight from 3 to 18 pounds depending on subspecies, according to Google) brought down the Hudson river Airbus. While a goose is not a drone, and it was a bunch of bad luck to take them into the engines, the Hudson plane was a couple thousand feet in the air going 200 knots or so when it hit them. Right where the d-bag drone altitude record YouTubers might be fooling around.
Combine small drone mass with big aircraft velocity and that can be a lot of energy to damage an aircraft. Might not happen often, but it could easily be very bad if it does.
I don't see a problem with trained, licensed commercial drone operators who would presumably be interested in following safety rules in order to preserve their business. Some acceptable FAA training and license program for that should be doable. It would also be good to require a commercial license to reign in the inevitable loss of actual pilot jobs that will happen when companies look to drones instead of aerial survey, hiring a local low-time commercial pilot to get your photos, etc.
Now, the old-school model airplane club folks probably do follow the rules about not flying near airports or above 400'. But the d-bags completely oblivious to the potential danger to real aircraft who are putting up their YouTube vids of their drone/model waaaay higher than 400' and the folks who are going to see those vids and follow suit need to be dealt with.
How about a rule where you can't buy a drone capable of going higher than 400' (or modify one to do so) unless you have some kind of model aircraft or drone license? Maybe you could require membership in a sanctioned R/C club to get the license. And if you get caught, you pay a penalty. While perhaps not many would be caught, local authorities can handle this on the rare occasion someone reports an ignorant drone owner is flying right next to the airport. (Gotta admit, not sure how you catch the YouTube altitude record guy hovering at the FAF for a runway)
Sure, it would suck for some retailers who might lose drone sales money for a while, and put a temporary slowdown on the toy / drone / R/C industry maybe. But maybe R/C hobby shops could make money by offering government-required drone safety classes as is done with gun safety training for concealed carry permits, etc.
