So, while the UK isn't an authoritarian police state it does have too many CCTV cameras and a large segment of the public likes them. This thread has had people asking for more CCTV; other threads suggested the local authorities using CCTV and human surveillance to check that people applying for a school place lived in the catchment area for that school.
We have a very large police DNA database and we see people resist attempts to scale it back. You even sometimes see large groups of people volunteer to have their DNA taken to rule themselves out of a high profile crime. And that's even though we know that a DNA database should probably have as many profiles of criminals as possible, and a s few profiles of non-criminals as possible, just because data handling.
A lot of these avenues of privacy were only really enabled by the growth of large metropolitan areas.
In smaller districts, you can't go to the inn and sleep with another woman because the innkeeper went to highschool with you and will tell your wife.
For the vast majority of human society, you had to try a lot harder to hide your activities if you wanted to go against the current social mores. It's not really clear to me that the level of privacy we can easily attain today, even if it is a social good, is not outweighed by the group benefits of social cohesion, and newly found benefits of catching criminals after the fact that CCTV would provide/encourage.
Only if all CCTV were to become publicly viewable at all times by everyone could we speak of it as a force for social cohesion, rather than a mechanism for amplifying differences in power.
Even in the case where CCTV is owned by the government, its operated by individual city districts.
It's not a singular invisible omniscient organization.
