They have taken pictures of the front of all first class mail for years.
I signed up for this service for a PO Box in another city.

But you are right, privacy left the building a number of years ago.
It still exists in other countries that can’t spend whatever they want to take over your life.
There’s a place on the Chile/Argentina border, that really isn’t claimed by either country. Life goes on there as it has for hundreds of years. Of course, no Starbucks, and probably much we like... trade-offs.
Other modern countries have other trade-offs.
Years ago, we traded ‘privacy’ for ‘anonymity’. We are merely ‘part of the herd’.
Chances are, if you go out of your home, at least part of your travels are on video somewhere.
