Article I, Section 8 of the Constitution provides that Congress may establish a system of patents and copyrights to promote progress in "science and useful arts."
I didn't read further than that. Anyone who starts off with such a blatant misrepresentation of the US constitution's recognition of authors' and inventors' exclusive right to their writings and designs as sanction to grant reproduction monopolies is not demonstrating sufficient competence to review a book on the subject of monopoly.
Firstly, I wouldn't misrepresent it, and secondly, 'exclusive right' needs no qualification as pre-existing, natural, and as independent of the state as any other natural right.
It is a misrepresentation that the constitution grants people a right that they didn't already have.
It simply recognises the right they already have and specifies that congress should have the power to secure it.
Because the meaning of the term 'right' has now become distorted to mean 'legislated privilege', today it needs qualification. It didn't a couple of centuries ago.
