Yeah I think you have it backwards. I don't think anyone has demonstrated any actual harms from porn, but social networks regularly fuck teenagers up.
I definitely would prefer my children to watch porn than get bullied - or worse - on social media.
There's also the fact that I vaguely trust Facebook or Reddit to do a credit card-based age check or whatever. No way I'm giving any of my details to porn sites.
Stupid dumb law.
i'd go even further: since harm of unrestricted access could not be proven, existing restrictions need to be reversed.
> I don't think anyone has demonstrated any actual harms from porn
That's disingenuous and false. It's pretty common knowledge that pornography is not representative of real relationships, and because it's not actually emotionally satisfying, it takes regular consumers down a rabbit hole of increasingly extreme, vile and obscure content. Take a guess what that does to a developing teenager, essentially being educated by pornography. Not to say that it's not harmful to adults too, because it is.
But yes, government control, censorship and centralization of the internet is not the solution. Mandatory ID checks will not protect any kids, it will destroy the free and open internet.
I keep seeing people mentioning credit cards as a mean to verify one's age. My daughter is 11, but she have her own card with her own name since at least one year.
