Now there's not a person I know who could afford books that wouldn't buy a book they like rather than go to a library to get every time they want to read it, so it's a moot point on your part. As for recycling, that paper has to be refined and processed by recycling centers and paper companies, so in effect the paper is just going straight back to the original creator. Plastic bottles are different; sometimes they are processed into synthetic clothing, sometimes they are melted down and possibly used for various other recyclable plastic goods.
I don't even know where you're getting this idea that printing CDs and books cheats the authors. That makes absolutely no sense at all. The appeal of tour readers and concerts is actually seeing the creator, why else would you put up with all the other people there? Second, only so many people can go to a given concert at a given time; music tours are less profitable than selling CDs, or at least permitting payed download. That's PAYED download, mind. Musicians actually get some royalties from both of those (replace CD with books and you get the same thing with authors), but they get nothing from when a person makes a free download. A payed download, or buying a CD, gets pretty much the same result as free downloads for the consumer, only at a small cost, whereas a free download's cost is payed only by the creator, not the consumer; a relation which can be significantly harmful.
