Because the present day isn't packed with working libraries, public education certainly isn't free, and new and used bookstores are extortionate for the most part. I know that the things I ask for are not available, either through popularity or scarcity. My library is about 40 miles from a university campus with a functional library, I even visited there once, go me. But because it's a university campus, all of the documents I want are all out on loan or reserved. Now, if I try to reserve one, it actually costs me money and often takes a month or more to actually come into my possession. Therefore, the 'free' part of the library fails to apply to me.
