Well those ones might be, but the ones I want sure aren't. I have to moderate my book-purchasing to avoid over-spending. The library is pretty helpful (reservation fees are more than I'd like, but a lot less than buying); some years I draw a couple of hundred books. But a lot of them I end up buying. Got one in my hand that was just delivered minutes ago (the new partial biography of Jobs about his years outside Apple).
I guess where this train of thought is going is to point out that people like me do exist. I do spent a lot on books. I borrow a lot from the library. Your assertions come across very strongly suggesting that people like me are a rounding error. But I assure you, when I'm in the bookstore I'm definitely not the only person there. Between us we appear to be propping up entire publishing industries. Almost 80% of the sales are physical rather than digital (1); if we weren't here there would be nothing for you to pirate!
