How to Destroy the Book by Cory Doctorow

I've Cory Doctorow's How to Destroy the Book pop up in a number of places now and I keep meaning to read it.

The part I find of particular interest is called 'The People of the Book'.

We are the people of the book. We love our books. We fill our houses with books. We treasure books we inherit from our parents, and we cherish the idea of passing those books on to our children. Indeed, how many of us started reading with a beloved book that belonged to one of our parents? We force worthy books on our friends, and we insist that they read them. We even feel a weird kinship for the people we see on buses or airplanes reading our books, the books that we claim. If anyone tries to take away our books—some oppressive government, some censor gone off the rails—we would defend them with everything that we have. We know our tribespeople when we visit their homes because every wall is lined with books. There are teetering piles of books beside the bed and on the floor; there are masses of swollen paperbacks in the bathroom. Our books are us. They are our outboard memory banks and they contain the moral, intellectual, and imaginative influences that make us the people we are today.

Copyright recognizes this. It says that when you buy a book, you own the book. It’s yours to give away, yours to keep, yours to license or to borrow, to inherit or to be included in your safe for your children. For centuries, copyright has acknowledged that sacred connection between readers and their books. We think of copyright as something that regulates things within a bunch of buckets—DVDs, video games, records—but books are more than all of these things. Books are older than copyright. Books are older than publishing. Books are older than printing!

The anti-copyright activists have no respect for our copyright and our books. They say that when you buy an ebook or an audiobook that’s delivered digitally, you are demoted from an owner to a licensor. From a reader to a mere user. These thieves deliver our digital books and our audiobooks wrapped in license agreements and technologies that might as well be designed to destroy the emotional connection that readers have with their books.

Copyright has become complicated. Where are the lines between owning a book and renting it in print or digital format? Is 'copyright' the enemy here, or is 'Digital Rights Management'? Isn't copyright supposed to protect people? At what point does it stop protecting creators and limiting audiences?
