There is lots of porn that credit card companies and proccessors don't want to touch. Plenty of kink sites have had problems with them, porn sites have blanket restrictions on keywords like hypnosis and shadow ban certain kinds of legal content in order to not get hamstrung by financial restrictions.

Also there are plenty of blackmarket goods that are heavily restricted and legally punished without good cause, and I do not believe just because something is "illegal" that it is automatically bad.
