Getting that way, I think it’s more of a culture than the state though. The main reason there’s so much CCTV is that nobody wants to be the one person or shop on the street that doesn’t have it, it makes them the soft target.
As for the online safety thing, most people seem to be in favour of it. Most parents say they’ll do anything for their kids and they think that giving up some privacy is a small price to pay when there are so many problems with kids and mental health these days. Personally I think the legal stuff is doing far more damage, things like influencers pressuring them to always look like models, adverts convincing them they need the latest iPhone, etc. How often do you hear about issues from watching porn? The long term solution is education
Also, age verification could be done in a more privacy respecting way than constantly requiring someone to scan their personal details; some kind of certificate and RSA type time based code. I picture it something like the government confirms your ID and gives you a certificate, you use that to authenticate to some kind of time based ticket service, which you then give to a company to prove you’re over 18. They know you’re old enough but have no link back to your ID.
