Since Thiel talks a lot about "monopoly theory" it's probably worth reading some of the people who've been talking about this for longer than Thiel's been in business (i.e. before the late 1980s). The two most prominent are Michael Porter and Warren Buffett. Buffett's annual letters to shareholders make excellent reading, and the book Understanding Michael Porter is a very good summary of Porter's thoughts.

This "theory" has been around for well over a century. It is just a rewording of a very mature understanding of product positioning and competitive advantage. It is nothing more than a nuanced understanding of Marketing 101.
