> But governments enjoy on a pretty broad support for this

No they do not. They do an enormous amount of PR trying to convince people that they have it, though.

In the real world when there is a ton of support behind a position, you see representatives of it all over the place and they are pushing the agenda and the coverage. In the world of online age verification, you just see a bunch of lame duck politicians using procedure to sneak policy changes in and keep objections from being heard, and a few government contractor-surrogates writing op-eds (that they haven't read.)

When puritans go on the march, they're actually pretty loud. Most of the anti-social media people are hippy-dippy upper-middle class liberals who curse "screens," completely believed Cambridge Analytica's PR and think that Trump rules through mind control - who will be bothered by the end of anonymity; and the remainder are angry online right-wingers who think that they were censored by and as a result of social media. They're not marching together, they're not marching to have people identified when they're using the internet, neither of them are even prioritizing social media right now and they aren't putting pressure on anyone.

The fact that it's so unpopular is why there are lame ducks doing it. They're just assuring their fortunes on the way out, and the person on the way in will pretend like they had nothing to do with it even though it will be will be passed and implemented on their watch.
