This argument justifies CCTV surveillance of all public places.

Is that what you intend to be arguing for? In any case, there needs to be more nuance in the discussion than a one-liner.

I think the quantity of surveillance matters. When it’s just a few places, then it’s a minor intrusion on liberty. When it’s a lot of places, it’s a major intrusion that will facilitate the (further) rise of authoritarianism.
