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.

The government can surely improve the quality of life for some, but I prefer Liberty to quality of life.
Why wait? Move to Congo today! The "government" is in name only!

What? Why aren't you going?!

Oh, right, you're full of shit. You only can only claim you prefer liberty to quality of life (which is a bullshit false dichotomy in and of itself -- think about it for five seconds!) because you're living a pleasant life. Nice going, Internet Warrior.
