Just requiring it for social media companies is probably enough of a win to not have to pursue any further. We require age verification for sports betting and things like that, I'm not sure why we wouldn't do the same or some variation of that for other massively addicting products that we know as a matter of scientific study have a very bad impact on some number of kids.
It will spread to everywhere else if we allow it for social media. In Australia for example, mandatory age verification has already spread to video games.
Because it's not about children but requiring identification to speak online.
Indeed, social media companies seem to big proponents of the US legislation.
