That would made a pure state like 1/sqrt(2)( up + down) into a mixture of states up and down, which gives different results than the pure state when measured in another base. Deutsch illustrates this already from the two slits experience. Keeping the “ignorance” interpretation would make that ignorance interacting at a distance, and consciousness or absence of consciousness would “act” on matter, even non-locally (and FTL). That is far too much more speculative than multiplying and differentiating the relative histories. Nature likes to multiply things, like the molecule of waters in the ocean, the planets, the galaxies, and why not, the relative histories (given that it explains what we see, and what mechanism already predicted) “Many histories” is the less “magical” explanation, and it requires only that an observer has some memory of repeated experience. And then, as I said, the whole of QM eventually becomes explainable as a confirmation of the many computations which are realised in Arithmetic, as logicians knows since the 1930s.
