It's not a good argument. Sale of ivory creates demand because it's a sale.

We could make it illegal to view images of ivory (with the logic that this might lead to a sale), but most people would consider that a step too far.

Viewing images of ivory is not harming an elephant, though. With CSAM, the image is the abuse – you'd be viewing the actual harm event. So consuming CSAM is more like purchasing the ivory yourself.
