I'd be more careful about asserting that about economists. Economists are much more likely than most people to be anti-IP, and IP abolitionism is a respectable opinion among mainstream economists (see Boldrin & Levine's Against Intellectual Monopoly for the most prominent example. Now, "most economists" are not anti-IP, because most economists have never read a paper even touching on the economics of IP. And while the literature is pretty damning, it's not one of those integrated conclusions of the field that every economist gets taught in school, like the idiocy of rent control.
