You're kidding right? Your phone was a stationary dumb object that only made and recieved calls if you were there to answer or use it. Your post was sent by paper and a million ways existed to avoid having it traced to your home or to you.

In no real way are these comparable to the deeply granular, deeply rooted 24/7 surveillance of movement, habits, contacts and nearly anything you like, that's today possible against any normally digitally connected person who doesn't take pretty extreme steps to avoid it (steps that by themselves make that person stand out as unusual enough to soon be flagged) I could go on and on with all the ways in which the tracking is pervasive and applied to most of the things we do today, and how none of that existed so autoamtically before the last 30-40 years or so.

Nobody with half a brain here is referring to some bucolic pastoral existence, simply to one in which the tools for tracking were just not like they are today, and if any government wanted to apply tracking of the kind that's pretty much turn-key constant now, it took unusual effort, staffing and specialized procedures.

You're either being deliberately obtuse or have no sense of perspective or idea of what you're saying
