You're right about the proofs, there should have been sources included. The book might be more thorough... I think you're oversimplifying a field you're not familiar with though, it's like a non-hacker saying that all you need to store data is to set up a microsoft Access database, and you're good to go. It's correct, but misses a lot of problems and subtleties.
