I think this is underappreciated ethical dilemma, rather like Typhoid Mary. I don't think that Wilhelm Reich thought of himself as a quack, or a fraud - he was more of a kind of technological mystic. While he himself was doubtless earnest, this kind of thing really is memetically dangerous - Scientology, for example, is a deliberate and successful attempt to weaponize it. Even now, people do crazy things like "seed" areas with "orgonite" to dispel "negative energy" - that is, they litter the ground with bits of metal encased with resin. A whole religion of woo, just from a few years of exposure to Reich's ideas.
So what is one to do with someone who is earnestly good-intentioned, highly charismatic, and completely stark-raving mad?
Ignore them as you should any other crackpot, charlatan or fraud. Don't waste your energy, time or money on them except to be entertained.
You should research Wilhelm Reich[1], a student of Freud's who came up with the term "orgone", who fled to the US to escape the Nazis only to have his writings confiscated and burnt by the US government, which imprisoned him until he died.
