I'm brave enough to say what I am sure some people are thinking.
If a pedophile can have access to a machine that generates endless child porn for them, completely cutting off the market for the "real thing", then maybe that's a step in a positive direction. Very far from perfect but better than the status quo.
The ideal ultimate solution is to develop a treatment that pedophiles can use to just stop being pedophiles entirely. I bet most pedophiles would jump on such a thing. But until that magical day maybe let's explore options that reduce the harm done to actually real children in the immediate term.
