The benefit is that instead of two rules for quantum behavior 1) the Schrodinger equation 2) the born rule , that contradict each other, you just have 1) the Schrodinger equation, which you already accepted. There is also a higher level goal that also motivates him > the quest for quantum gravity is being held back by physicists’ traditional strategy of taking a classical theory (such as Albert Einstein’s general relativity) and ‘quantising’ it. Presumably nature doesn’t work like that; it’s just quantum from the start.
