Yeah, I mean why does the government get to tell me how I raise my kids? I wanna put them to work, drive heavy machinery, and marry them off to 90 year old "founders" all I like so stay outta my business.

Oh I'm sorry you're totally right, we need to ban working, driving heavy machinery, and marriage to protect your children. Because that's what this is all actually about right? Sock puppet guy has made that quite clear, his goal is to ban all porn.

The difference is that in the cases you mention, the government is protecting kids from bad actions that parents might take.

Requiring age verification won't stop a parent from giving a kid access to porn. And, frankly, if a parent wants to show a teen porn as a way to educate them about what can be bad about it and what the dangers are, that's a private matter between the parent and the teen.
