“Property rights are the most basic of human rights and an essential foundation for other human rights." - Milton Friedman wrote in his memoir Two Lucky People with his wife Rose.

Patents and copyrights are the legal implementation of the base of all property rights: a man's right to the product of his mind. Every type of productive work involves a combination of mental and of physical effort: of thought and of physical action to translate that thought into a material form. The proportion of these two elements varies in different types of work. At the lowest end of the scale, the mental effort required to perform unskilled manual labor is minimal. At the other end, what the patent and copyright laws acknowledge is the paramount role of mental effort in the production of material values; these laws protect the mind's contribution in its purest form the origination of an idea. The subject of patents and copyrights is intellectual property. ... Thus the law establishes the property right of a mind to that which it has brought in existence. - Ayn Rand, Capitalism: The Unknown Ideal
