This sounds very Wittgensteinian. In terms of his philosophy of language, what we have here is a "metaphor gone wild". You take "intellectual" and "property", you put them together as a metaphorical phrase that on the face of it seems meaningful and semantically sound, and people start believe that there's actually such a thing; that it's not made up word-lego.
It takes careful awareness to language to be able to point this out, as Stallman does. Just because there's a word for it, doesn't make it meaningful.
