I enjoyed the doom-saying for the simple reason that the business intelligentsia are making noises about how negative interest rates are not only okay, they're the natural state of affairs. Having the libertarians come out of the woodwork to scream the end is nigh is a welcome counterpoint, methinks. The author has a legitimate beef here: if the government is going to make the loaning of money for profit economically unviable they're going to severely pervert the incentives of the marketplace and perverting the incentives of the marketplace for libertarians is like pissing in the holy water for catholics. I agree with the basic point that the government manipulating the economy is a long way from the free market we supposedly espouse. I disagree that having command aspects in the economy is the end of western civilization.
