You are confusing facts with an appeal to the authority of wikipedia. However, I can still make my arguments using the wikipedia instead of Hans-Hermann Hoppe.Markvee, clearly Hans-Hermann Hoppe knows little more about these issues that you do if he thinks the post office is a public good. Likewise with his other examples. I suggested that you google the term “public good” to try to learn something about the concept. Clearly, you are not a good judge of sources (hell even Wikipedia would have been better). I would take the time to educate you if I had not wasted far too much time doing so in the past. You have your beliefs and I have facts. Sort of like the difference between a religious person and a non religious person. By all means keep your beliefs. However, if you ever do decide to educate yourself, there are plenty of sources you could start here http://en.wikipedia.org/wiki/Public_good. If you decide not to, that is your business.
From: http://en.wikipedia.org/wiki/Public_good
Definition of public goods:
"This is the property that has become known as Non-rivalry. In addition a pure public good exhibits a second property called Non-excludability: that is, it is impossible to exclude any individuals from consuming the good."
So called public goods that have been provided privately:
You stated that Hans-Hermann Hoppe knows little about these issues if he thinks the post office is a public good. Likewise with his other examples. However, lighthouses are provided as an example of so called public goods by both Hoppe and the wikipedia article you referenced:
"Common examples of public goods include: defense and law enforcement (including the system of property rights), public fireworks, lighthouses, clean air and other environmental goods, and information goods, such as software development, authorship, and invention."
I use the term so called because public goods because Hoppe used historical examples of alleged public goods, as in not alleged by him. He argues that the distinction between public and private goods is illusory in the paragraph entitled "The problem of determination" from my original reference. In your wikipedia reference, Murray Rothbard questions whether defense is a public good:
"'national defense' is surely not an absolute good with only one unit of supply. It consists of specific resources committed in certain definite and concrete ways—and these resources are necessarily scarce. A ring of defense bases around New York, for example, cuts down the amount possibly available around San Francisco."
Why public goods are a waste of resources:
"Regardless of the method of providing public goods, the efficient level of such provision is still being subjected to economic analysis. "
One possible analysis is that so called public goods are most efficiently provided by the free market.
Jumping back to my original reference to Hoppe's essay, Hoppe also references Rothbard in arguing against the notion that production of public goods is an exception to primarcy of free market efficiency: “... such a view completely misconceives the way in which economic science asserts that free-market action is ever optimal. It is optimal, not from the standpoint of the personal ethical views of an economist, but from the standpoint of free, voluntary actions of all participants and in satisfying the freely expressed needs of the consumers. Government interference, therefore, will necessarily and always move away from such an optimum.”
