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.

Universities waste tens of thousands of dollars on students to study "modern art" or "sociology" because both the universities and the students know they don't have to pay for it.

At the same time the people who want to waste money on this shit because they feel they need to prove something complain about how most tax comes from low income earners.

I have an idea, why not ditch subsidising universities and reduce tax on the poor by the amount of money you saved?
