I fly in my back yard all of time time. I'm well within shotgun range of 4 neighbors. Does that mean I'm automatically an asshole and automatically trying to get a peek at my neighbors daughters? Or is the possibility that I'm learning how to fly, in MY backyard, during reasonable hours? Why should I need to go get permission from my neighbor to fly a quad in my back yard?
What's wrong with the criminal process as it is today? If the neighbor thinks I am taking pictures of his daughter (whether from a quad, or from my deck using a camera with a nice zoom on it) he can call the police, and they can do their job. If I'm disturbing their peace (by flying my quad, using a chainsaw, or playing loud music) there are legal avenues for that too.
None of these situations need to involve shotguns or willful destruction of property. People taking the law into their hands is never a good thing.
Where in the thread is anyone saying you can't fly over your own property? If you fly your drone over their property and within a few tens of feet of people and dwelling windows yes your drone deserves a shotgun blast because you are being an asshole. No one is saying you can't do what you want on your own property as your straw man arguments suggest.
