Disregarding that you completely fail to understand OP’s question; physical books suck. We used then until a few decades ago because we didn’t have anything better now we do. It’s called an e-reader and it’s superior to dead tree books in every single way.
The user-experience of physical books is pretty bad. They are bulky and heavy, unlike an e-reader you can’t keep 1000+ books in your coat pocket. You need an external light source, which limits where and when you can read. If you want to read a new book you have to go to a physical store or library (both have extremely limited selections due to the aforementioned bulkiness) or you have to order online which takes at least a day for delivery. With an e-reader I can pick a book and start reading it 10 seconds later without even leaving the comfort of my bed.
Then there’s small things like full text search.
