The software does the decryption, not the user. The files on the file system stay encrypted. To create a clear text copy to pirate, the user would have to write their own decryption program. And yes, this would be possible. Again, the goal is not to make piracy impossible. At some point in ANY process, the user must be able to read the book, and that means clear text will be visible / accessible / copyable.
I can't think that publishers really believe that a "perfect" DRM system is possible. What they want is protection from casual copying; a system that mimics a physical transaction: one person buying a unique copy of a book.
The system I'm proposing, I think, meets that need, while not limiting my personal use of the books I buy.
