CCTV coverage is already high in London, and increasing everywhere. Recognition software (not just facial) is getting quite good.

Cash can mostly be tracked unless you just trade with black/grey market sellers. Adding RFID to notes and mandating readers on cash registers would already be feasible.

Home devices (TVs, DVRs, even fridges[1]) increasingly have microphones and other sensors, so it'll be hard to be sure you're not being recorded even when talking to friends in their living room.

I don't see any trends in that direction right now. The institutions of both western democracies and most other societies have proven themselves wholly ineffectual at curbing any of the vast overreach by both intelligence agencies and police.

So it will just happen again. (Meet the new boss, same as the old... Animal farm etc) without all of them being dismantled too. And revolutions of that scale rarely work out well for anyone in the short term.
