If people are exposed to stimuli, they will pursue increasingly stimulating versions of it. I.e., if they see artificial CP, they will often begin to become desensitized (habituated) and pursue real CP or even live children thereafter.
Conversely, if people are not exposed to certain stimuli, they will never be able to conceptualize them, and thus will be unable to think about them.
Obviously you cannot eliminate all CP but minimizing the overall levels of exposure / ease of access to these kinds of things is way more appropriate than maximizing it.
