Query: Refutation of Hilbert Space Fundamentalism   According to the "Hilbert Space Fundamentalism" Thesis, all features of a
physical system, including the $3$D-space, a preferred basis, and factorization
into subsystems, uniquely emerge from the state vector and the Hamiltonian
alone. I give a simplified account of the proof from arXiv:2102.08620 showing
that such emerging structures cannot be both unique and physically relevant.
