Where you see "consumer convenience," I see "breakdown of law and order" that this technology could help ameliorate.

I think we're just coming at this from different biases. You see the risk of abuse of power as much, much higher than street crime (if I take your "occasional" literally, then I humbly suggest you haven't experienced it to the level my relatives have). I see the threat of street crime as much, much higher than risk of abuse of power (because while those abuses do happen, they are so rare relative to the street crime this system could prevent that it's a viable tradeoff).

I agree.
