Yes I agree the way the UK is going about this is fucking silly and unlikely to even work, however I haven’t seen much debate about the motive behind the act.
I feel like this community has generally been pretty critical of the porn industry and particularly the effect of the massive proliferation of easy to access internet porn on young men (“porn brain” was a pretty common term around here). But when the UK tries to ban it I’ve suddenly seen a lot of defense of teenagers right to see pics or boobs on the internet.
I would also point out this is an ML dominated community, most people here are pretty fine with socialist governments censoring content or restricting access to good that are deemed harmful to the common good. But I have noticed a trend on here where when a liberal capitalist government tries to do the same thing everyone suddenly start sounding very libertarian about porn/booze/slop movies/what have you.
Because this isn’t about actually protecting children and bettering society, it’s about using “protecting the children” as a cudgel to ban things they want to destroy or suppress. It isn’t just about porn, it’s also going to be used to attack minorities, LGBTQ people in particular. Every capitalist accusation at socialist countries is a confession. They accuse places like China of “suppressing free speech” and “controlling their citizen’s thoughts and behaviours” because that is exactly what they want to do.
To answer your question directly, no. I don’t think there is a “better implementation” of such a thing in a capitalist country. At best it would be less mask off, and would only open the door for more harmful policies years down the line, instead of months down the line. But the end goal of this isn’t to help, it’s to harm. “Better implementation” of deliberately harmful policy isn’t actually better for people, and doesn’t improve things, it just hides the harm better. The purpose of the system is what it does, not the flowery language they use to cloak it.
