Even models with unrealistic assumptions aren't useless. They still teach you how to think carefully about a problem. If you can't solve the simple model with unrealistic assumptions, how are you going to solve the more complex model with realistic ones?
In the case of the much ballyhooed "37% rule", I blame the math journalists more than the mathematicians.
