Even if you'd fold them open to the point they almost break and individual pages get loose, it still does not yield the book unreadable. I've read books like that. No, it's not exactly the best experience, but as long as all pages are there and in order then I still don't really see it as a major problem, there's already enough thrash in the world.

(not addressed toyou, but don't feel like making separate comments and it in agreement with OP): Likewise for the yellow pages problem another commenter mentions. If it's just the color the only real effect is, I think, a bit less contrast between the letters and background. I seriously wonder if this has an actual effect on reading. I get that if you somehow attach, for whatever reason, value to paper being white, you consider yellow paper as less valueable. But imo this is in most cases purely artificial value: for reading the content matters way more than the medium. Those hundreds of years old yellow books do have value because of their content, and are perfectly readable.
