How would that work? do you want to provide government id to watch porn?

And how is this helping since it's not going to work overall (other sites, torrents, etc)

Come up with a better solution, provide a proof of concept and yes regulatory agencies / governments will take notice. People like us work in these agencies. Let's propose better ways of achieving the same goal of reducing porn exposure to minors - not keep bashing the initiative taken.

The vague potential harm of sex doesn't justify the concrete harm of abolishing digital privacy. Further, it's just sex. Equating imagery of legal, natural activity with physical danger is an error.

It is blatantly dangerous to justify stripping citizens of their anonymity. The lawmakers who proposed this are oppressors. They are the danger to our children.

This approach would be much more effective than making ridiculous demands of privately run websites or attempting to ban VPNs. And yes, some kids will find a way around whatever system you set up; the solution to that is not to turn the whole of society into a police state. Some kids will always find ways to break the rules; many years ago when I was young I knew plenty of kids who found ways of getting their hands on alcohol or even worse things. Somehow society still exists today.

The bigger problem is if the UK has an extradition treaty with the country you live in.

Then you're into "what about all TLS connections" which can be used to send traffic, so you have to do TLS interception at scale, which is a very non-trivial problem to try and solve.

Then you're into non-TLS encrypted protocols, so your only option there is to block anything you can't intercept.....

At that point you've pretty much broken Internet access in your country, might as well just chop the cables :P
