I'm interested in defending libertarian ideals. So I wanted to share this
post from the Volokh Conspiracy:
One of Michael Kinsley's criticisms of libertarianism is based on "externalities" caused by government financing. He argues that people should not be allowed to drive without wearing seatbelts because their risky behavior creates an "externality" - a cost that they don't bear themselves. The externality in question is the fact that government may end up financing their medical treatment.
…
The libertarian solution to this problem is to eliminate the government financing that created the "externality" in the first place. If you are worried about taxpayers having to pay for smokers' medical expenses, then argue for the elimination of government subsidies for the treatment of illnesses caused by smoking. Ditto for injuries caused by not wearing a seatbelt…In some cases, eliminating the government financing externality by eliminating government financing may be impossible for political or technical reasons. In such situations, there really is a difficult tradeoff between individual freedom and taxpayer interests. However, if government financing externalities are your true reasons for favoring any given type of regulation, you should at least consider the possibility of getting rid of the externality without restricting freedom.
That's a nice point, but it oversimplifies by assuming that the government financing externalities can be eliminated. Sure, a direct externality can be removed; in the example given above regarding seat belts, we can eliminate "government subsidies for the treatment of injuries caused by wearing a seatbelt."
However, some externalities will always remain merely because of the existence of government in the first place, no matter how much government financing is eliminated.
There are more government financing externalities implicated when an individual decides to forgo seatbelt usage than just the subsidies for treating injuries.
For example, people injured in accidents who were not wearing their seatbelts tend to suffer greater injury and have longer recovery times than those involved in accidents while wearing a seatbelt. Thus, injury to a non-seatbelt-wearer impacts tax revenues, if he is an hourly worker out of work for a long period of time. He's not making income, so he's not paying taxes. Or a severely injured non-seatbelt-wearing teenager recovering from his injuries is not attending school. If he's held back an extra year because of it, government financing will pay for an additional year of public schooling that he wouldn't have needed had he been wearing a seatbelt. You see my point: eliminate the direct government financing externality and there are still legitimate justifications for regulating seatbelt use, which stem from government financing in other areas, ones that even libertarians may see as perfectly legitimate exercises of government authority.
None of that is to say that therefore government regulation is justified whenever the behavior of an individual has an impact on society as a whole. From the "circle of life" point of view, after all, every single thing that happens to me at least theoretically has at least some impact on you. (This is a world, remember, wherein my growing wheat for personal consumption on my own farm impacts interstate commerce!)
I just wanted to point out that one of the things I find fascinating about libertarianism is that, although we can address and remove the immediate and direct externalities by reducing the amount of government financing in the world, the nature of a society is that the exercise of individual will in any way will always impose some amount of externalities on the rest. It's a zero-sum game! The policy choices involve weighing when the impact on society is greater than the cost to liberty.
A libertarian will simply require a much heavier and more direct "cost" on society to justify government intrusion than would, for instance, a socialist. More on this issue here.
And speaking of libertarianism, I'm with Ilya Somin: More money for "beer and skittles," less for Ron Paul.
And he would have gotten away with it all, too, if it weren't for those nosey kids!
