>There's no downside for the wealthy with this tech,

Wealthy people break petty laws (the kind of stuff these systems make it possible to crack down on) all the time. There's a reason you never see the cops running a DUI dragnet at the rich people boat ramp. The wealthy do not want to be subject to surveillance dragnets because while many people can pull strings to get out of trouble very, very, very few people can afford to pull string with the regularity that would be required if the rich were subject to a police state.
