I'm only talking about equal access to exactly the same whatever the state already has access to, not anything new or extra.

The surveillance already exists, and is already being used only against you, rarely for you.

If you or I shouldn't have unrestricted access to it, then neither should anyone else. If it is to exist, and anyone is to have access to it, then so should you and I.

I wish that I could believe this was possible. In pretty much every government on earth such a scheme would be made illegal on some pretext well before attainment of said critical mass.

Plenty of private entities are already recording like crazy, so I assume it's the publication bit that you're thinking would be made illegal?
