Now that the 70-ish year experiment is over, we’re simply reverting to the way we’ve been since time immemorial.
The timeline you present is backwards because you misunderstand privacy as a binary. For most of human history we were extremely private to almost everybody in the world, and that's only changed relatively recently.

- at a medium, you will have annoying and intrusive identity checks required to use many common websites
- at a high medium, you will not be able to use a non trusted computer and identity stack: get on a windows, apple, or google device and use their identity services in their browsers, or else you cannot use the internet
- at a maximum, all activity you and everyone takes online will be monitored and faithfully tied to your or their verified identity. This total loss of privacy will result in a total loss of freedom of speech and assembly online.
That last point is the direct aim of the people driving these laws.
