there isn't a problem to solve. the fact legislators want to do this is the problem. quibbling about how exactly they're gonna implement the torment nexus is secondary to the goal of resisting the torment nexus.

like, if your whole thing is "this is happening, its self-evidently about surveillance, and we can do nothing to stop it" and you start proposing ways for us to be surveilled "safely, securely, and privately", you are pro-surveillance. you are supporting the bills, right now, with the rhetoric you're using. like, imagine doing this about any other political issue.

"i don't support the death penalty, but we can't stop the government from implementing it, so here's the way I'd murder prisoners."

"we can't stop them from banning abortion, and I hate that, but I'll suggest we put the limit at 10 weeks. that seems reasonable, right?"

your idea for "solving the problem" involves doing the thing that both restricts what information people can access, and tracks their legal identity, but in a way that is maybe marginally less stupid than tech illiterate legislators can manage. the fact that you would be fine with the bills if the intent was just to ensure kids can't access "pornography" in a private way kind of reveals your biases here. it would not be a good idea even then.

what counts as pornography is socially defined. a tool which allows the selective restriction of pornography is also by definition a tool that encourages the redefinition of pornography to encompass whatever it is governments don't want people to learn about. especially in the US, it would become a tool for the censorship of minorities, the banning of books, and the removal of queer people from the internet. that's why these laws are being proposed. its not ambiguous at all. like, even if it is inevitable it will pass, the priority doesn't then become "how do we make this bad idea more efficient?", it becomes "how do we subvert this unethical restriction on our communications?". assuming that we can do nothing to stop this ensures that we won't. its a good thing nobody's buying your bullshit.
