Listned to it, and while I think that it is always correct to guard against any kind of naive hero worship, especially in the political realm, I am not at all impressed with Hoppe here.  

There is nothing that he said that Milei would disagree with ideologically.

The entire critique reduces to a complaint about the speed and scope of change.  That is to say, Hoppe is criticizing the real, practical work of implementation from the perch of theoretical purity, from a conceptual laboratory devoid of any kind of real-world constraints or consequences whatsoever, and he is doing so without offering any kind of support or involvement whatsoever.  It is a bit of a bad-faith criticism, uninformed about the particulars and uninterested in the success.

At the very least, consider that Milei is not an absolute monarch, but a president, bound by a constitution, with a party that has an extreme minority of lawmakers for representation, that is dealing with a country that was on the brink of hyper-inflation, that is institutionally captured by extreme criminality and corruption and unbelievable grift.  I am extremely surprised that Milei has not been assassinated yet.  

But yeah, I guess Hoppe can keep writing some books and keep his hands clean and sit in the wings and wait to see if the battle is won before he comes down from his mountain and gives his approval.
