That is your copy just as if you'd bought a book at your local bookstore.

No it isn't. The book does not come with a license you must agree to before starting to read it. If such a book does exist, and it might, it would be a very notable exception that would make it more like software and less like a book. But to equate ownership of OSX to ownership of a book is incorrect and misleading.

Sorry.

Authors have tried. And guess what, such licenses were deemed unenforceable.

In both cases the authors derive all of their rights from copyright.
