Is Criticizing The Kochs Unlibertarian?

Brad Delong snarks that supporters of the untrammeled free market have no standing to criticize the Koch takeover of Cato:

[T]he delicious irony is that the arguments against the Kochtopus–powerful and convincing arguments–are not libertarian but rather Burkean, communitarian, and social democratic ones, and thus arguments that no true libertarian could ever possibly make.

Julian Sanchez finds Delong's position ridiculous:

I’m not arguing that Congress should intervene somehow. I’m arguing that exercising those rights as they seemingly intend to is a bad idea; that their direct control would, in itself,  be damaging to Cato’s credibility; and that I’m not interested in working for the Republican talking-point factory that all evidence suggests they envision. Like rain on your wedding day and other infamous Alanisisms, that’s kind of crappy, but not "ironic" in any recognizable sense. I realize progressives think libertarianism is just code for uncritical worship of rich people, but as that’s not actually the case, the only irony here is that people think they’re scoring some kind of gotcha point when they’re actually exposing the silliness of their own caricature.

Corey Robin counters. James Grimmelman piles on:

The irony here is that the nation’s preeminent libertarians—who ought to be exquisitely attentive to freedom of contract, institutional design, and observing the letter of the law—couldn’t get their rights right. They built this Streeling of libertarian thought, with its $20+ million annual budget and world-wide reputation, on a shareholding structure that is either actually or nearly under the control of people who do not share many of their values and have not for decades. The entire enterprise may well have been for years only one death away from Koch domination. If so many libertarians are now so worried about a Koch takeover, one has to ask, why have they spent so many years building a brand with an unshielded thermal exhaust port?

 Jessica Flanigan's riposte:

Who’s really the hypocrite here? Critics on the left seemingly delight in attacking the most extreme version of libertarianism, and then attributing that extreme picture to every libertarian they meet. … I think one reason for the progressive resistance to the more moderate versions of libertarianism stems from the fact that moderate libertarians are in many ways beating them at their own game. As Glenn Greenwald and Matt Stoller have both brilliantly argued, libertarian politics is currently more in line with progressive values than popular progressive political candidates.
