Bob, either I'm missing something, or you are.

If you pick a single point in configuration space in the position basis, nothing has a specified momentum. If you pick a single point in the momentum basis, nothing has a specified position. If you pick a single point in the polarized-45-degrees basis, nothing has a specified 90-degree polarization. Decoherence gives us a preferred basis for our blobs of amplitude but that preferred basis is changing all the time and different for every particle. How's this single-point trick going to work? And what does the epiphenomenal single point do that makes it realer than the causally powerful wavefunction?
