This has been a fascinating series of posts. You are suggesting a realistic interpretation of QM. Do you take the real universe to be the (single) point in the universal QM configuration space, along with the single complex value of the universal wavefunction? Or, since the wavefunction is a function of all possible configurations, are those other configurations somehow real as well (which would be some sort of multiverse theory)? Quantum mechanics certainly allows wavefunctions comprising superpositions of different configurations. Are these superposition states not fundamental?

No, the universe is an (evolving) amplitude distribution over configuration space.

I'm not what "superposition state" means, but my guess is that the answer to "Are these superposition states not fundamental?" is "Yes they are".
