Great, more DRM is always so nice. There was a talk at defcon this year by a Chinese researcher (I forget her name) where she A) spoofed the GPS signal so that a GPS-restricted copter (which I guess already exists in China) could fly in a no-fly zone and B) convinced a bunch of copters flying in a park that they were, in fact, suddenly in a no-fly zone, and so they promptly crashed. It is not the job of my machines to police my behaviour on behalf of the government. If a machine is physically capable of doing something, there should always be a way for me to do it. A warning (e.g. A restricted airspace alert) is fine, but the technology should not presume to override my commands based on its (easily confused) interpretation of the law. Users should control machines, not the other way around.
