> no, there really doesn't need to be

Bob the Bully doesn't like you. Whenever you leave your front door, Bob will fly his drone over your head while its onboard speaker continuously curses you out with TTS. Whenever you want to have a romantic moment with your boyfriend / girlfriend, Bob's drone will be watching through the nearest window.

If you ask Bob to stop harassing you, he'll laugh and curse you out in person. If you sue Bob, after thousands in legal fees the court system will say "You're SoL; there's no law that says Bob can't do what he's doing." If involve the police, they'll say "We can't do anything because no illegal activity is occurring." If you shoot down the drone, you'll be sent to prison like the guy in the video.

You only have one realistic option in this situation, "Just put up with it." This certainly seems like a bug in the law that ought to be patched.

That's already highly illegal, it's called harassment and invasion of privacy and there are laws against it. Laws specifically against voyeurism, unlawful video surveillance, harassment and stalking, intrusion upon seclusion, nuisance...

This would easily meet the bar for a harassment complaint.
