Intellectual property is different from land. Land is rival and exclusionary: if I have it, you cannot; and my having it prevents you from it. Most economists define "public goods" as non-rival and non-exclusionary. A sunset is an example. That also applies to an idea. The difference is that sunsets exist in nature and ideas are man-made.
Back in the 1970s Durk Pearson and Sandy Shaw (writing as Skye d'Aureous and Natalee Hall in their Libertarian Connection) insisted against even Ludwig von Mises that beauty must be created, and truth must be discovered; so, those, too are economic goods. When they are created by human action, beauty and truth deserve protection under law.

That being true, it is also true that beauty, truth, and intellectual property in general are not land. You can buy an artist's painting and never share it; but once you do, you cannot take back the experience. Anyone who saw Henry Ford driving his automobile could make one of their own. More to the point, the idea of a "horseless carriage" was practicable since the development of steam engines in the eighteenth century. Several experimental devices were constructed and tested, including those of Karl Benz, Wilhelm Maybach, and Gottlieb Daimler all of which used internal combustion engines. The automobile was not unique in having a long pedigree.
