Maybe my position can be clarified a bit better: We both want to minimize this problem and stop it from happening. My argument is not that we should ignore the problem, my argument is that banning these things is not the most effective solution.

My view is that we are likely to have a greater impact on stopping this problem by using tactics other than banning them.

I'm sorry to hear about your aquantances phishing attacks. There are parallels to be sure, but Phishing attacks are a clear deception, and everyone upon being phished will agree that they have been done wrong by, so it is easy to make these illegal; you don't create a black market for people who want to go out and get phished anyway. Unfortunately the same is not true of people who purchase quack therapy. Most will continue to think that their money was well spent.
