You could certainly describe excess consumption of food, drugs, and/or sexual novelty as degenerate behavior. But GP appears to simply be referring to either consumption of or payment for pornography as a degenerate activity.

The argument is any modern pronography represents an excess in sexual novelty compared to the baseline.

If you take the baseline to be a Neolithic life experience, then I don't think it's indefensible at all.
