Yeah, I don't have nearly such a problem with simulations. You don't have to hurt somebody to make them, you're not embarrassing anybody by distributing them (it's typically illegal to distribute any private photograph that the subject does not want distributed), it's not at all clear that simulations increase the likelihood of acting stuff out in the real world, and they may even have a net positive effect over no porn at all. In my own experience with child sexual abuse, if the perpetrators had had access to simulated porn, it's quite reasonable to think that maybe there wouldn't be as much of a problem.

Although I believe that it's harder to detect fake ivory than it is to detect fake child porn, below a certain age.

And I also believe that legalizing videos of illegal acts encourages the illegal acts, provided the videos are willingly being made by the criminals and they are being used for entertainment as opposed to journalism or analysis. But this is really just a belief, and I do understand that you have the opposite belief.
