Matt Ridley joins the ranks of cornucopian libertarians with a similarly error-ridden and cherry-picked set of arguments.
I found a harsh review and a followup by George Monbiot:
The Man Who Wants To Northern Rock The Planet
Matt Ridley's Rational Optimist is telling the rich what they want to hear
These are in the book reviews, environmentalism, and freedom through technology indexes.
[Addition: I've found several more harsh reviews, and placed them at: Reviews Of Books Related To Libertarianism.]
