I can't address each of your points so long as one equates the responsibility and risks (all the trappings included) of operating while being on-board an aircraft with that of flying a remote controlled aircraft.
There's a magnitude of difference.
I'd have to hear to give reply but I suspect that the APPLICABLE (not total) differences are not so great.
But, also, consider the relative potential for harm an "incident" each brings.
Massive burning crash with up to hundreds of deaths and possibly bad or even worse damage and toll on the ground. Damage in $millions plus many human lives.
Vs
Someone gets clunked on the head, some plastic hits and dents something. Damage in the, what, maybe couple thousand. Maybe maybe maybe a signal human casualty (none to date).
Not being sarcastic or silly in my above examples and figures.
Yet the aircraft with potential for far less harm is far greater restricted than the truly scary one.
