Might be vulnerable to classic salami tactics, though. Once we arrive at a general consensus on new norms that expect age verification online, we can just legislate it to ID users as a step 2.

Maybe wait for the next terror-attack before pushing for it, but it's an easy fix to a culture that already accepted a layer control against the user. The end user will only perceive a small difference in whether they provide full ID or just verified age information.

I want to believe that some supporters of age verification are not cynical. However, whatever good can be achieved through age verification seems such a small win, compared to the dangerous precedent it sets for the internet in general. I cannot get my head around it.
