Biology and chemistry exist as disciplines because, even though the laws of physics theoretically explain everything about the universe, it is completely intractable to use them to do so — and it turns out we can construct explanations of the universe at higher levels of abstraction than fundamental physics, and then reason using those explanations. Your argument seems to be that physics is all we need.
