This quickly gets into the zone of absolving parents of their responsibilities to oversee their children's education and rearing in the manner that they choose (porn is bad vs. porn is not for you until you're older, etc) How much media in our society is "not for children" but are still easily accessed by children? And how much of that happens because parents aren't paying attention? Porn is just an easy target, especially in America. I'm not saying we should do nothing, but I don't think this is effective action. It's actually impossible to effectively manage this with laws and centralized legislation (I would argue this is performative more than anything else), and the more of this we have, the more of a false sense of security you give parents, and the less responsibility they feel they need to have in guiding and supporting their children and helping them learn the reality of the world around them.
