Yeah, but a national license plate surveillance system that lets a single police officer observe all of the movements you and your family members make every day for the past few years is not a single police officer making a plainview observation of you driving down the road.
And it's clearly a power that threatens liberties, you cannot have a free society when a government has that power.
"Palantir, what are the names and home addresses of all of the people that were at the pro-Mamdani rally, show me places that many of them go to in common, I want to find where these criminals are having their secret meetings."
Probably not in voice-to-text form, but this power is already in the hands of some US agencies, in part thanks to the national ALPR system.
