Poor people don't read books. That is one major reason why they stay poor.
I have a house full of paper books, but you really would need a mansion with a large library, to fit in many more. Most are rotting away in the basement or in boxes in the closet. I do the middle-class thing and go to the library, but they are also space-limited, so some books I like borrowing eventually get taken out of the shelves.
E-books are much better, as you can have as many as you have digital storage space, but I didn't want anyone to change them from underneath me, so I went online and built software that keeps books on relays and allows every part of them to be cryptographically signed and the changes tracked. Which solves that problem.
And then, anyone with a cell phone can have access to any book I also have access to, since the relay is public. This was better, then going offline, with my paper edition of Frankenstein, and sneering at the commoners who can't afford to buy 500000 paper books.
