No matter how many steps of security do have: There will be a master password/passphrase, and you shouldn't write it down in clear text! So better find a way (some kind of secret algorithm, stored in your brain) to reproduce your master pass.
Taking away the most versatile and most commonly used tool shouldn't be the way to go.
If we keep up these obsolete paradigms, students will be forced to stick with ineffective handwritings off whiteboards. Their documents go to the trash after school since the serve no purpose anymore and they use up far too much space.
