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.

Its still just an opinion which lacks an objective truth. Or rather, can you state as an libertarian what conditions would have to be met for libertarianism to be disproven?
