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.

It's amazing how many Americans think that it's illegal to stop somebody who is committing a felony.  In fact, citizens are legally affirmed to have arrest powers when a felony is occurring.  Of course, you should be sure about what's going on, in case you're quite mistaken about who did what and how.
