When the UK age verification legislation was being debated I recall people saying "don't worry about unintended consequences, it's not like you'll be have to show your ID to random websites! Someone will show up with a reasonable methodology. You'll be able to e.g. show your ID at a shop and get an anonymous token.".
And plenty of people, including myself, thought "this is so dystopian it couldn't possibly happen".
It did happen, and it's as bad as the doomsayers said it would be.
