The state doesn’t regulate these things to protect people, it does so to manage risk to itself. Porn, guns, gambling, tobacco, alcohol, etc., are tolerated so long as they are contained, taxable, and politically useful.
Regulating porn is this system likely trying to move the needle on declining birth rates. You can look to a host of pro-natalist efforts in China as the likely inspiration.
And without a doubt, overreach by governments will continue.
What’s less clear is the claim that pornography is inherently harmful to children’s development or wellbeing, the research is mixed at best. And the justification that age-gating websites and apps is purely about safety remains deeply unconvincing.
So then either this effort is misguided, a hollow gesture for optics, or a small piece of a broader agenda that hasn’t been made explicit. It just seems to me that this is creating a lot of chaos for a hollow gesture.
