Are you suggesting that the system is efficient enough, and the users of it are competent enough, that a live moving no-fly zone would be placed somewhere that a drone in the immediate vicinity would be informed and be disabled?

I have my doubts. I would guess one "popping up" would at least be delayed such that it's pretty pointless by the time the drones are notified. Annoying indeed, useful (even to the ne'er-do-wells trying to enforce this crazy stuff) not so much.

DJI has (or, at least, had, a few years ago) a no-fly system that was updated via the Internet. Maybe it's not live, but then what would be the point of these no-fly zones? Just so ICE agents can shoot your drone down with impunity? If they didn't need license to execute people in the streets, I don't see why they'd need license to shoot down a drone.
