Ludwig von Mises writes in Human Action on the nature of copyrights and patents:
If there are neither copyrights nor patents, the inventors and authors are in the position of an entrepreneur. They have a temporary advantage as against other people. As they start sooner in utilizing their invention or their manuscript themselves or in making it available for use to other people (manufacturers or publishers), they have the chance to earn profits in the time interval until everybody can likewise utilize it. As soon as the invention or the content of the book are publicly known, they become “free goods” and the inventor or author has only his glory. (p. 657, Scholar’s Edition)
The analysis is as clear and sound as anything else Mises ever wrote, and the implications are obvious. That the “digital” information economy provides the means to easily make and distribute copies does not change anything; in fact, the faster pace of the market affects all industries and products (however at varying degrees).
One might wonder what could possibly be wrong with being an entrepreneur in the market. The answer is: Nothing. Unless you already enjoy a politically enforced privilege, of course, because then you would prefer and push to keep it. That is the nature of privilege, after all.
