Hawking knows that the desperate clinging to a formulation of a single reality as being the so called "absolute truth" does not hold, so he said what he said. For, Hawking is aware of the fact that any formulation of reality is dependent on context and on specific levels of analysis; and all the time he wants to get a specific answer at this specific question: in Schroedinger's equation that provides wavefunctions that give probabilities for quantum events, what were the derived wavefunctions wavefunctions of?
You see, Schroedinger had the feeling that the wave aspect of quantum phenomena was primary and that therefore the wavefunction represented a kind of vibration in an electromagnetic field. However this is not the case: the wavefunction is not real in the sense of a physical system as such a system is conceived in classical physics. So in fact Hawking joins hands with Born and says that the wavefunction is just an abstract mathematical entity that can be used to extract information about nature. In other words, "If one wants to assign to the wavefunction its own independent reality, then one has to solve very crucial problems" is my interpretation of Hawking's quote that you gave. Clearπ
Leaving Hawking aside, have you an argument that is yours?
