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.

Libertarians fail to acknowledge the ethical problems with the libertarian system. Yes science could get more done if it could test on anyone, but we cannot choose who should be sacrificed for advancement. So we only allow those who volunteer. And even they are reviewed to see if a crime of ethics is not being commited. (an example would be letting a drug addict volunteer for a methadone test.)
