The old question: "why did human beings form societies?" So that the individual is better off, or not? Is it fair for society to restrict the rights of of the creators of goods in digital form more than the rights of the creators of goods in physical form, just by saying "it is for the public good"? Are we ants, do we just live and die for society?
For me it makes no sense to think of copyright as being simply to encourage people to produce more. That is a great side benefit, but in the end it must be there to help protect the individual's rights. And no, anyone who was not written a book has no rights to the book unless being given permission to do so.
