Una buena entrada de Stephan Kinsella en el Mises Blog sobre la propiedad intelectual y la estructura de la acción humana. Enlaza varias referencias sobre el debate. Copio dos párrafos:
To have successful action, then, one must have knowledge about causal laws to know which means to employ, and one must have the ability to employ the means suitable for the goal sought. The scarce resources employed as means need to be owned by the actor, because by their nature as scarce resources only one person may use them. Notice, however, that this is not true of the ideas, knowledge and information that guides the choice of means. The actor need not "own" such information, since he can use this information even if thousands of other people also use this information to guide their own actions. In other words, if some other person is using a given means, I am unable to use that means to accomplish my desired goal. But if some other person is also informed by the same ideas that I have, I am not hindered in acting. This is the reason why it makes no sense for there to be property rights in information.
Material progress is made over time in human society because information is not scarce and can be infinitely multiplied, learned, taught, and built on. The more patterns, recipes, causal laws that are known add to the stock of knowledge available to actors, and acts as a greater and greater wealth multiplier by allowing actors to engage in ever more efficient and productive action.
