Thinking that isn’t going to lead to more actual children being exploited is extremely naive.

That particular argument doesn't hold water. We don't generally subscribe to this kind of argument.

The general principle behind the specific argument you bring up here is this: All expression which is likely to inspire someone toward illegal action should itself be illegal.

CP is likely to inspire some people toward child abuse. Child abuse is illegal. Thus the distribution of CP should be illegal.

We don't do this anywhere else.

Descriptions of non consesnual violence are likely to inspire some people toward non consensual violence. Non consensual violence is illegal. Thus the distribution of all descriptions of non consensual violence should be illegal.

If we take this seriously, we have to ban action movies. And I am not even getting into the whole porn debate...

No, the only valid reason for banning the distribution of child porn which I can think of, lies in the rights of the victims. The victims were abused, and their image was used without their consent. Without them even possibly being able to give consent to any of that, or the distribution that follows.

So anyone who shares child porn, is guaranteed to share a piece of media which shows someone being subjected to a crime, while they couldn't possibly give consent for that to be recorded, or shared publicly. Making it illegal to share someone being a victim of a crime, without them being able to consent to that being shared, is a reasoning which has far fewer problems than what you propose here.
