I do see what you are saying. And if that's the way things go, then we'll be in a dystopian nightmare, and I would expect the civilization to crash and burn and humanity to go extinct. If that's how you feel about the future, that's on you.
I choose to believe that we will figure out how to survive and thrive. What you are describing is already part of the world we live in, it's called the 4th Amendment. We have the right to be secure in our papers and effects against unreasonable searches and seizures, and this shall not be violated and no Warrants shall issue but upon probable cause supported by Oath or affirmation, and particularly describing the place to be searched and the persons or things to be seized. This applies to day, to all financial transactions and records of communications. If legal authority believes that a crime has been committed, they can search and bring what they find to a court of law. If we don't believe in that anymore, then we have given up on nation states and we should prepare for hell on Earth. I'm not ready to go there.
