It's not necessary about books being sacred. It's about throwing out things that can serve more people for much longer. This paper still absolutely has a use, contrary to what you say.
Don't you have a store for second-hand books around? Or a library that would accept book donations? People will gladly make use of your old book stock. They won't have to overpay, you will help the environment if nothing else, and some book nerd will finally find the specific edition of a specific book you have.
