The only goal of the comparison to string theory was that it's an alternative theory that an educated observer should judge on its own merits. I'm saying that the background of one's introduction to economics should be based in the mainstream, just as one's intro to physics should not be based in mainstream physics vs string theory (saying nothing of how advanced the intro curriculum need be). My fundamental point is that alternative theories are invaluable and essential, but being conservative and sticking with the mainstream is generally well-advised for beginners. Once you're confident in your grounding in the mainstream, you can approach alternatives with a critical, well-informed eye.
