Less likely to prevent sale than just require adherence to FAA flight rules as already required for any other flying object, like drones. FAA both has all kinds of flight restrictions around many types of facilities, puts out all kinds of NOTAMs (Notice To Arimen) for temporary flight restrictions, and nearly anyone flying anything is required to check and follow these for every flight. Additionally, commercial drones have geofencing so they won't even fly within restricted areas.
If you fly your drone over restricted mil bases, you can expect a lot of enforcement to show up really fast, including weapons aimed at your drone. They'd have no problem enforcing the same kind of rules for a person flying over an area where deadly force is authorized for trespassers than they would for a trespasser on foot or vehicle, and you'd be a much easier target, and much larger audible signature.
I wouldn't worry that this concern will kill the industry.
