> You can finish reading your friend's favorite book or put it down if you don't like it. Neither are you economically compelled to read it by your workplace or forced to build work on top of it that will become difficult or impossible to modify/maintain if you bin the book.

Economics does sometimes compel you to read books or other material as a condition or expectation of employment. It is difficult to get a good job while being illiterate and many jobs require reading huge volumes of written work. Work in law or journalism springs to mind as economically compelling people to read a lot even if they they might not necessarily want to.
