I like the overall method - love the kid and give them logical consequences to mimic the real world. Easier for them to pay for it at 9 than 19! However, some of the examples of what to do were a 'no way' for me. If my kid is scared at night and needs comfort, I'm not going to play the get over it so mommy can sleep card. Seems unnecessary. Take some of the scenarios with a grain of salt and adapt to your personal tastes.
