This is the first time my poor communication skills have been interpreted as a sign of my superior intelligence. I think I'm ready to become a professional expert consultant!
I was abstracting Richard Stallman's argument to its (il)logical structure: P and ¬P are whether the license restriction is enforceable, etcetera. "Erosion" was talking about people who, seeing free software as a good idea, begin to adhere to Stallmanite orthodoxy (which is, largely, philosophically-unsound): that was not aimed at you, but at Richard Stallman himself (the Ur-Stallmanite, we could say). I saw this as generalising your criticism. I didn't notice you were making a broader point about the law, so this was somewhat of a supercalifragilisticexpialidocious non-sequitur; thanks for clarifying your point.
