Will Wilkinson is upset

If a smattering of libertarian ideas can bring it [the system] all down, then the problem isn’t really libertarian ideas, is it? If the integrity of the economy in your preferred model requires a high level of ideological conformity, you might think to reconsider the wisdom of harnessing it so thoroughly to democratic political institutions meant to accomodate pluralism.

That’s not the part where he is really upset.  He’s also upset here and here.
