The UK has had a great firewall for decades - try going to a kiddie porn site or a torrent site and you will be unable to connect.

If they had instead gone on a "porn sites that would obey the ID law need to flag themselves via this system and ISPs/phone providers should block them by default and only the account holder can enable it", then they would actually have some leverage over mindgeek (or whoever), and would be able to remove that subset.
But instead people in the UK now either use a vpn to bypass it and thus will also bypass this new law, or go to far dodgier sites which ignore the requirements that the commercial ones follow, driving teenage boys (and adult men) into the arms of sites with incest, bestiality, snuff etc, rather than this generation's equivelent of playboy.
If they are seeking out vile material like incest, animal rape and sexualised murder then the blame lays entirely on them, not the government.
I mean what is even your point? Male depravity is unavoidable, and men are mindless ejaculators with no free will to curb abnormal sexual behaviours?
You turn people off the professional sites which can be held accountable and they end up on the dark side of the internet.
America saw the same thing when the puritans banned alcohol last century, people ran right into the arms of organised crime.
No-one is forcing them to buy a VPN and visit pornography websites.
