I think there's an obvious slippery slope here, and it's visible in how these sorts of age verification requirements are implemented. Specifically, requiring a government ID to access, creating a log of who/what/where/when.

The slippery slope comes from someone then asking the question: "Well, we already require an ID to allow someone to access porn... so can we require it for other things online where people have less desire for privacy? Why shouldn't we require an ID to post to social media, or participate in online video games (especially those violent ones!)"

The slope I see, is once you set up a system for ID verification and require it for a primary thing people want to keep private, it becomes easier to mandate it in other areas where privacy is less demanded.

Concern about that slope would be a nonissue if the laws mandated adult sites tag themselves as "adult content" for trivial filtering at the household network level, instead of establishing and normalizing the ID verification regime.
