I've noticed over the years that any mention of child porn on an internet forum usually leads to a few posters making arguments that take the side of people with pedophilia. First, it's not easy to overcome, like any paraphilia or fetish, and if you don't hurt children you aren't a criminal. Second, merely distributing images doesn't directly harm anyone or conclusively promote harm. Third, not having access to images might increase acting out in the real world. Fourth, animated simulations could be tolerable substitutes.
At any rate, I find pedophilia so abhorrent that these kinds of arguments never really crossed my mind before I started reading forums. Which means I don't think they're entirely useless. I could probably tolerate legal simulations.
