If iPhone cases are a waste of money, then Apple should feel comfortable including a 4 year warranty on the screen and case that includes physical damage, no?

If iPhone cases are a waste of money, then Apple should feel comfortable including a 4 year warranty on the screen and case that includes physical damage, no?
