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?
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”.
