Fight the New Drug
As if we needed any reminder just how out of touch with reality these people are, the oldest profession (porn is essentially just prostitution by proxy) is somehow being portrayed as something new and scary.
Or to put it in more factual terms, the earliest known piece of human figurine art is the Venus of Hohle Fels, described by its discover as "This [figure] is about sex, reproduction... [it is] an extremely powerful depiction of the essence of being female". This is not at all unusual for Paleolithic art. 50,000 years doesn't really seem to count as a new phenomenon worth getting in a panic about. We've been making pictures of boobs and dicks for pretty much as long as we've been making pictures, and that should say all that is needed about how successful attempts to ban them are likely to be.
