I'm aware of this alternate formulation of QM, but think that has problems of its own. This is why I tried to phrase the gedanken experiment in terms of plain vanilla QM which has no decoherence. The truth, I suspect, lies somewhere in the middle - ie a decoherence-like effect will probably prove essential to stabilise the classical world.
