This is an extremely narrow definition of pornography that completely excludes drawn or written material, much of which is produced by individual creators without any intention of making a profit.

I truly mean this with no ill intention, but if you have such fantasies, please seek therapy, not porn.

It is not psychiatrically possible to "cure" someone of a kink. Even if it were, the standard for a psychological trait requiring psychiatric care is that it negatively impacts the person or those around them. Most people who have this kink are not going to meet either standard.

You might argue that "it negatively impacts them even if they don't think so," but you are not in any position to make such an assessment about them and it's frankly condescending to insist to someone "no no, you're definitely damaged, you just don't know it." I know people who have this kink. They aren't time bombs and they aren't victims. They're people who happen to enjoy an extreme scenario within the bounds of fantasy. You're making a snap judgment you're completely unqualified to make about people you know nothing about. I'd urge you to read the literature about the psychology of SV fantasies before you weigh in on the subject. No investigation, no right to speak.
