If the key is obtained over the net in a secure manner each time the book is opened, then it gets harder for the user to get their hands on it. It also makes the key book-specific and possibly random (rather than having the same, guessable key for the entire library). That seems to be the way that Adobe was going with their latest ADE encryption scheme. I think that they, like webroot, were seeing ebooks as something that you read on a connected computer using an app (that can be updated at any time). They didn't seem to be considering connectionless devices with fixed firmwares, like e-ink readers often are.
