Seems like this was a thing before drones too, though. Call in a fake bomb threat, leave an empty bag suspiciously lying around, etc. All things that could asymmetrically disrupt the airport. Granted, the chance to get caught is smaller with drones, but it's still fairly risky. I guess the only defense here are publicized arrests to dissuade the "prankster" category of attacker and the fact that statistically only very few people are crazy enough in the first place to try such an attack.
