Why do you want to punish people even more instead of trying to educate them and help them? You and me probably do not make mistakes in this subject: but we have to admit we are both lucky and got enough education/insights to be able to handle security 'right'. Most of the population are not that lucky.
Forcing users to type out passwords does not educate them, or even encourage good habits. All it does is frustrate people who already have good password management habits, and encourage those who don't to keep (re-)using passwords that are easy to remember and quick to type.
