I explain that background freedom in quantum gravity automatically leads to a
    dissociation of the quantum state into states having a classical 3d-space. That
    is, interference is not completely well-defined for states with different
    3d-space geometries, even if their linear combination is.

    The dissociation into 3d-space geometries still allows for interference at
    small scales, but precludes it at macro scales. It grants the possibility of
    classical-looking macroscopic objects, including measuring devices. Counting
    the 3d-space geometries automatically gives the Born rule.

    But the wavefunction collapse turns out to be even more ad-hoc. Fortunately,
    the dissociation entails a kind of absolute decoherence, making the
    wavefunction collapse unnecessary. This naturally leads to a new version of the
    many-worlds interpretation, while solving its major problems:

    1) the classical-3d-space states form an absolute preferred basis,

    2) at any time, the resulting micro-branches look like classical worlds, with
    objects in the 3d-space,

    3) the 3d-space geometries converge at the Big-Bang, favoring macro-branching
    towards the future,

    4) macro-branches stop interfering, even though micro-branches can interfere,

    5) the wavefunctional becomes real by absorbing the complex phases in the
    global U(1) gauge,

    6) the ontology is a state vector uniquely dissociable into many gauged
    3d-space states, each of them counting as a world by having local beables (the
    3d-space geometry and the classical fields),

    7) the density of the classical-3d-space states automatically obeys the Born
