In a typical illicit market, producers are motivated by money, so craahing the (black) market value essentially stops the problem. I suspect, as I think you do, that this is not the case with CSA, where most producers are primarily motivated by their own urges. Having said that, the current (legal) theory of CSA is that each act of consumption re-victimizes the original victim. If you believe that framework, then artificial CSA could plausibly be a net positive by reducing the secondary damage done by distributing recordings of actual abuse. More speculativly, there may be social dynamics at play in the production of CSA. If you have a group of pedophiles dedicated to CSA, they group likely provides social pressure on its members to produce it. With easy access to artificial CSA, those social pressures could be lessened, which could result in less actual abuse.
