Why is libertarianism so infallible?

It is due to it being the application of political science. It does not permit failed policies to be continued fruitlessly year after year with idealistic fervour, it is next to impossible for anyone surrounded by fierce libertarian critics to continue clinging on to lies. It is a purely functional machine, lubricated with justice and fueled by free speech.

If libertarians really think that corporations are more emboldened that government, please list a prominent corporation, and what legislation particularly emboldens it.  I want the specific law, with the specific corporate policy that capitalized on the passing on said law.
