It is important to remember that being Libertarian is not the same thing as being a "corporate cheerleader." And that can be what Rumsfeldia was accurately described.
Rumsfeldia, despite its lofty rhetoric, violated the principles of laissez-faire all the time. From stealing intellectual property, to heavily regulating television networks. It was a blatant oligarchy of corrupt corporations, whose actions were essentially protected in a court of law. Rumsfeldia didn't get rid of the regulatory state, the regulatory state merely favored Rummy's corporate backers.
I read libertarian websites like Reason, and the viewpoints they express are not a single-minded attack on "socialism". They also heavily criticize government intervention ON behalf of big business as well, and make pretty good arguments that the problems we see in the economy are a result of government regulating ON BEHALF of big business.
I can picture Libertarians defending laissez-faire, while also being very hostile toward cronyism as well.
This may sound odd...but, where are the Trumps currently, specifically Donald?
