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.

One of the reasons libertarianism is so infallible is that the typical libertarian is a teenage boy. There's absolutely no empathy for the common person who actually lives in the world, and there's always an unrealistic expectation that anyone can become a millionaire unless they're lazy welfare cases. As such, there's no real attempt at forming a valid argument, so there's rarely anything palpable to argue against.

What's the possible benefit of libertarianism? That we would have fewer taxes to pay? We can go through each part of government spending, showing how almost all significant spending  is necessary (though efficient). We need the military, because having fees paid to mercenaries through non-governmental means is absurd (and would be ineffective even if possible). We need to pay interest on the national debt. There you go, just with those two you very well aren't going to be close to living a tax-free life.

Someone needs to pay for roads somehow. If you want to buy some delicious Florida oranges in Chicago, they have to get to the store, and if the government isn't making the transportation infrastructure with your tax dollars, you're going to be paying it anyways with higher prices.

Do we need an FDA or EPA, so that the average life expectancy can be competitive with the rest of the civilized world? Libertarians won't admit it, but they really don't think so. They don't have any sympathy towards people who don't have the money to fly around on their own private jets and feast on Swiss chocolate. The rest of us peasants can either starve or eat pesticide- and hormone-laced food (at higher prices than now, because instead of paying subsidies with your tax dollars, you'll pay them directly).

An appendectomy costs $2500. Do you have that kind of money laying around? A lot of people do, a lot don't. Libertarians believe that if you don't, you should just die on the street. The garbage men can pick up your corpse. That's what's so cool about libertarianism- it's so gleefully evil. There's absolutely no desire to benefit anyone other than oneself.

For objectivists (who don't know they are yet, because they don't have the attention span to read Ayn Rand), wouldn't that make sense, though? I mean, I could argue against objectivism, but that's really a different topic. Here's the problem: it doesn't even benefit yourself. Forget the remote possibility that you won't have a million dollars to retire on by the time you're 40. In four or five years, you're going to graduate from (public) high school. What then? Does your mommy and daddy have enough money to send you to a private college? No? Oh well, I guess instead of being an engineer, graphics designer, or whatever else you could have been if you had gone to college, you can just dispose of dead bodies (from starvation and easily curable diseases) that are laid out on the street for minimum wage (haha).

This gets to the crux of libertarian thought. To the libertarian, it will somehow all turn out okay. Once all the public universities are gotten rid of, more private universities will pop up. They'll do all the same stuff, except better and cheaper because they're private industry, and since there's more of them, an increase in supply will lower the prices enough that ordinary people will be able to afford them (without government grants, even). I'll agree, the cost will definitely go down, but why would you think that it would go down enough for the average family? Really, weren't public schools created because private industry couldn't meet the demands of society (a well-educated workforce that could do something other than farm, which incidentally results in greater individual prosperity)?

Then the libertarian comes back with his not-so-secret weapon: a hideous distaste for civilized society. If demand can't keep up, he says, let them all be peasants! Somehow, it'll all work out. When there's enough people in the work force that honestly can't do anything other than flip burgers, the wage for them will go up, they'll be able to send their kids to private school, and society will be better off for it! There's a problem with this kind of thinking, guys: it's shit. Nobody over the age of 19 buys it, for good reason.

The best quote so far:
>People's lives will be ruined

That pretty much sums up libertarianism.
