Yeah I agree - it is a very difficult balancing act for sure. Perhaps I have a strong belief that manifests as bias when it comes to access to information - the right to read.
LLM's are an isomorphic distillation of human expression. Writing and knowledge compressed into probability curves. In my view, an LLM is similar to a public library. Public libraries DO have children's sections. But many children also gain knowledge and understanding from the other sections of the library as well. I believe this to be an important part of a well-rounded up-bringing - access to knowledge and the freedom to explore one's own curiosity and interests.
Of course there exists knowledge and information that is age-inappropriate. That's why my parents cared about preventing me from seeing too much violence in movies when I was young! But they certainly weren't ever required to prove that the TV was being used by a minor by submitting their driver's license to the cable company, and if they failed to comply, the service would be cut-off with no explanation at any moment. As far as the balancing act goes - that feels a bit off in my opinion.
