Libertarianism est arrivee

These are the heady days of libertarianism.  It has arrived, and will shortly fill the law reviews.  Green and glorious, the center of all right-thinking people of good faith.  (Well, perhaps faith is not required.)  But here it is.  We know this because Cass Sunstein is writing about it, and Sunstein is an inerrant indicator of high intellectual fashion.  Whatever it is he is writing about, that is at about to be the thing to write about in the legal academy.  No matter the quality, there he is.  Civic republicanism (oh, sadly, a life measured in only a few years), web communities (which he got completely wrong) and so on.  So, exploit it while you can. And, one hopes, more serious thinking will get some attention as well.  Or not -- any reference by Sunstein to Otsuka? 
Whatever Friedman's merits as an economist, in political theory he was almost always out of his depth.   His efforts in philosophy were uniformly failures.  But that should matter greatly as he was an economist and it is that field in which we should judge him.  Like most of Sunstein, this too is about two inches deep.
