I don't think it's about rationality. If it was how do you explain actual art ie drawing being something not everyone could do? It has more to do with people trying to frame an algorithm or logic behind these "dark arts". This article is an example of it. If everyone was to follow the same set of rules then sooner or later the market is filled with look-alike negating the effects. That is not something which would happen rather something already happens. So while the logic might be entirely fine it's over saturation kills that logic.
