There’s an argument around growing / shrinking a market here. Have you ever experienced morbid fascination? Some people get addicted to the experience of horror (I don’t mean the genre). This arguably creates a new demand for something that even those demanding it would not otherwise have had any interest in.
I think you’re right about the dangers of giving authority over what does and doesn’t get censored, but there are also very real dangers on the other side of this. You don’t make consuming heroin normative, because you don’t want to make it easy to fall into an addiction by accident for those who are more prone to do so. The more harm the addiction causes to society as a whole, the more prerogative you have to protect people from accidentally becoming addicted.
