Do you want number plates? Mine have never helped me get anything except for parking fines, but lawmakers decided being able to visually and uniquely identify a car for the purposes of law enforcement was more important than my privacy because it enabled widespread use of this dangerous and strictly regulated machinery. You can own a car without number plates, you just can't drive it on a public road. Presumably similar with this hypothetical kill switch. Requiring compliance with rules for access to a shared resource doesn't seem that ethically challenging when you think about it.
