The Trump administration has been working overtime trying to build databases of people in this country. Leaving no stone unturned, legal or otherwise. I vaguely remember a time when American conservatives were against precisely this, often as a first principle. Maybe that's just an idealized memory on my part.
The American conservatives who can afford to be are effectively exempted. When they're not flying around on private jets, the ownership and metadata created by their cars, phones, etc. are obfuscated by layers of shell corporations.
The other ones are simple and/or deluded and think these sorts of policies won't ever come for _them_. (To their credit, under the current regime they're actually correct about that to a certain extent.)
Spoiler: They were never against it, just biding their time.
Yep, just in different flavors based on ideology. For example, forced labor requires logging & tracking of pregnancies. Anti-trans folks want gender identity on the books to gatekeep who can teach in schools or enter bathrooms. Same for preventing same-sex marriage. Folks railing against voting rights want more and more checks to prove who you are and where you live
