As I hinted in my other post, I think it may just be a preliminary step to prepare for a world where drones (and otherwise flying devices) could become much more ubiquitous than they currently are - not to address the current situation, which indeed doesn't pose any significant problem at the moment.
So how far up do you "own" the airspace above your house or land? If an Amazon drone decides to fly over my property to fulfill a delivery, do they have to pay me? Do I have the option to use it for target practice? 
The simple answer in most countries you don't own any airspace.
Rules for overflying private property are a country by country thing but in Oz providing you conform to the relevant ANO (Air navigation order) for the R/C aircraft or Drone (I draw a real distinction between the two and I own both) it is absolutely ok to do so. HOWEVER what is not OK is to invade the privacy of people in that property and that is where the rise of Drone usage in particular idiot owners of them has caused the need for increased regulation. In Oz my Drones or R/C aircraft are LEGAL so shooting one down would be illegal not that we generally have that sort of issue. Even if one of my airframes came down on private property it remains mine and 'legally' I can retrieve it and if the property owner refuses then they would be effectively at fault. But the simple answer is you shouldn't be over private property if you can't clear that property if it goes wrong and it does.
Way back in time well over thirty years ago when I started flying R/C usage was in the main constrained to registered flying fields and was very much a Hobby as the airframes were scratch built from plans or 'sometimes' from a kit for those who could afford them. The exception to this was those of us who flew Gliders as we tended to hang out on Hills and Cliffs ridge soaring. Come forward 30 years and MOST now buy ready to fly or maybe screw the gear in airframes and almost no one builds from plans or from scratch and unassembled kits are as rare as rocking horse poop and cost more than prebuilt RTF airframes.
Add to this ease of access has seen a major decline in numbers joining these formally peak national bodies so by number they clout with National Governments is in decline. This apart from cheaper access came about with the increase in Electric Aircraft has made it noise friendly enough that you could drop down toy your local park and have a fly without upsetting the noise sensitive ears of the neighbors. That said I have had a noise complaint and the Police dropped around when I was flying an Unpowered Glider from a Bungy launch

This get online and buy a cool thing because you can afford it doesn't give the numpty allegedly in control any clues on weather or what happens if or how should I behave around people, buildings etc so Governments who in the main used to reply on input from the R/C bodies have decided to go draconian whenever possible. Canada was last year brought in one of the most kneejerk set of dumbass regulations in the World not sure if it has been moderated at all since?
Like a lot of things in this world banning or tightly controlling them is easier than seeking a workable compromise or extending a former compromise that is/was decades old

The excuse of it will stop the bad guys is more than ever

you can buy a RTF unit already built that is not DJI or GPS locked strap an exploding rock to it and off you go. If you are really serious about doing harm from a distance you would use fixed wing (much higher speed and payload for way less $) and fly line of sight with that rock. 100MPH+ 2-3kg of exploding Rock and accurate at 500-1000m for a few hundred $ without a GPS on low frequency AM or FM and no where near the current Drone jamming gears range. This is where some of the fear and smear merchants and media just don't get it. This sort of device is decades old and harder to stop than a 'Drone'.
Sorry for being a bit long winded but why we are now here is the result of where we used to be and so called 'progress'
Good Luck to the USA mob if it passes I am sure our turn will come soon after
