Many authors write for most of their lives before they see success. Who is really suffering from copyright laws being longer than 20 years? Is there a giant void in culture because books go out-of-print? In cases of non-fiction and academics I can see there maybe being an issue with students not being able to learn, but with most fiction it's really ok to have to put some effort into obtaining a copy.

There are always new and amazing books being written. It's ok if some are difficult to obtain or abandoned. It's their creation and they can let it die.
