It's pretty much impossible, so we should stop trying. It's exhausting seeing politicians et al continue to push for age verification despite it being impossible to be even remotely effective. (I hedge because technically we could demand photo ID for every HTTP request, I guess, but I don't think that's ever going to happen.)
The best we can do is ask parents to raise their children themselves and teach children to be mindful online (as we expect them to be IRL).
In real life everything from porn to alcohol to cigarettes, and even movies all require ID. And it's super easy to bypass in endless ways, but those efforts have nonetheless been overwhelmingly successful. And I don't really understand the issue people have with social media and ID. You're already required to link your phone which is a massive invasion of privacy, and the sites themselves not entirely infrequently demand ID from accounts at their own arbitrary and whimsical discretion.
