The Libertarian Case Against Intellectual Property Rights
"A Dispute Among Libertarians
The status of intellectual property rights (copyrights, patents, and the like) is an issue that has long divided libertarians. Such libertarian luminaries as Herbert Spencer, Lysander Spooner, and Ayn Rand have been strong supporters of intellectual property rights. Thomas Jefferson, on the other hand, was ambivalent on the issue, while radical libertarians like Benjamin Tucker in the last century and Tom Palmer in the present one have rejected intellectual property rights altogether.
When libertarians of the first sort come across a purported intellectual property right, they see one more instance of an individual’s rightful claim to the product of his labor. When libertarians of the second sort come across a purported intellectual property right, they see one more instance of undeserved monopoly privilege granted by government.
I used to be in the first group. Now I am in the second. I’d like to explain why I think intellectual property rights are unjustified, and how the legitimate ends currently sought through the expedient of intellectual property rights might be secured by other, voluntary means.
The Historical Argument
Intellectual property rights have a tainted past. Originally, both patents and copyrights were grants of monopoly privilege pure and simple. A printing house might be assigned a “copyright” by royal mandate, meaning that only it was allowed to print books or newspapers in a certain district; there was no presumption that copyright originated with the author. Likewise, those with political pull might be assigned a “patent,” i.e., an exclusive monopoly, over some commodity, regardless of whether they had had anything to do with inventing it. Intellectual property rights had their origin in governmental privilege and governmental protectionism, not in any zeal to protect the rights of creators to the fruits of their efforts. And the abolition of patents was one of the rallying cries of the 17th-century Levellers (arguably the first libertarians).
Now this by itself does not prove that there is anything wrong with intellectual property rights as we know them today. An unsavory past is not a decisive argument against any phenomenon; many worthwhile and valuable things arose from suspect beginnings. (Nietzsche once remarked that there is nothing so marvelous that its past will bear much looking into.) But the fact that intellectual property rights originated in state oppression should at least make us pause and be very cautious before embracing them..."
