You're trying to use the Socratic method to show that the havingness of the book is a spectrum, and I'm taking the position of a hardliner who considers that "having the book" means having the original string of symbols from beginning to end, and anything besides that is not having the book. I'm trying to show you that your line of argumentation is uncompelling to such a person.

I was never using the Socratic method. I was asking rhetorical questions, and then gave the (my) answer at the end.

We just have different opinions about what it means to have a book. I think that having a copy of "Pride and Prejudice and Zombies" is more like having a copy of "Pride and Prejudice", than having no book at all is like having a copy of that book. You disagree and that's fine.
