The problem is that today there are very few private places, and it is very hard to get to a private place unnoticed. Private, secluded places are becoming rare as security cameras are installed. Even if you can find such a place, your trip to it might be recorded by security cameras and license plate scanners. Even if records of postal mail had been kept in the past, it would have been very difficult to make use of that data -- but data mining techniques are changing that.

"The internet is really not designed to keep communications over it secret or private in any way, and platforms like Google and Facebook are built on exposing as much private information about users as possible."

I once had this view, but I have come to see that it is flawed. Most people are not making an informed decision about this, and there is almost no effort to teach the background needed to make such an informed choice. What we are seeing are governments and corporations taking advantage of the general population's ignorance. It is not that people do not value privacy, it is that they do not even realize the extent to which they are giving it up.
