Radley Balko has written a characteristically astute critique of Chris Beam’s New York magazine article on libertarianism. I think Radley says all that needs to be said on the subject.
Instead, I’d like to throw out a few other approaches to the subject that might have worked better:
(2) A much more fun piece, attuned to a New York audience, would open with the Tea Party’s libertarianism and make a strong case for its hypocrisy: they call themselves libertarians, but here are the subsidies they love, the un-libertarian restrictions they champion, etc. This section would be tendentious and unfair, but that’s the fun of it. And then the piece would argue that modern-day New York city, for all its taxes and regulations, is the real home of liberty: look to the cultural freedom, and also to the entrepreneurial energy of Silicon Alley, etc. Bracketing whether or not this is fair, it would be a provocative piece about who really owns liberty.
(3) Drawing on Amar Bhidé and Tim Wu and Tyler, one could also write a straightforward piece on how Tea Party libertarians and minarchists are misguided because more freedom and more affluence and more government tend to go hand in hand. We get more free and less free at the same time, along different dimensions. Again, this piece might be boring, but not necessarily.
