Not raving, but drooling....
Sorry, couldn't resist the straight line you fed me there.
I liked the article you linked to. I don't entirely agree, but there is certainly a strong case there, and my examples of "monopolies" would be of the generally non-coercive kind with just a hint of cross-subsidy.
I don't neccesarily agree that the free market is an ideal arbiter of consumer good. I have suffered from some painful distortions of the free market over the years, but admit that government regulation has had some role in many of my pains.
Thanks for the link, but I'll walk my own road for now...
