This kind of argument works for classical thermodynamics too, where observing a particle in a gas collapses it's velocity distribution; where if we take a confined gas we can localize it (confining it within a tight space), only to grow uncertain about the momentum of constituents, or expand it, growing uncertain about the position. In other words, for any probabilistic physical framework it seems to me you are going to need to put a magical 'sampling' or 'observation' somewhere. Making this explicit is one of the reasons I like Bohm's formulation: https://en.wikipedia.org/wiki/De_Broglie%E2%80%93Bohm_theory#Relation_to_the_Born_Rule https://en.wikipedia.org/wiki/De_Broglie%E2%80%93Bohm_theory...
