Protection from media at the government level should not happen, that's the slippery slope. Very few policies aside from educate children about topics, has ever actually helped a child. This shit is about data and overlord control. Devices should not have age verification.
Very little good comes from arbitrary control, particularly based on age, and always has been that way even on other topics that are age restricted. Education is a far more effective means, and doesn't trample everyone.
