Is it even an attainable goal? It seems an NN with less than say 4 billion parameters will be able to do that. The cost of training will likely go down with more models being available. Unless we lock down the computing for majority of people, I don't see how we can prevent someone creating a CSAM model in their garage.

I don't want to see CSAM created, but the totalitarian control required is too much for my taste (and frankly it's preferable for that person to use NN than to go out and hurt actual children).

Not to mention even locked down technology is often being abused by the privileged.
