I'm kind of curious about scale vs nuance trade-offs here. Any solution big enough to help everyone will be clumsy. I don't know enough about what sort of experiences people have to understand the damage done, and it seems personal enough that regs will damage things, or not help
Personally, I'm pretty sure that any attempt to do anything will end up with far more collateral than helped people. I don't think anybody has the right kind of knowledge to ban porn in a way that doesn't end catastrophically.
