Which one precisely? Gleason theorem is enough, and it requires only that the Hilbert space is not too much low dimensional (>= 3). Then, with Mechanism, the “many” is as natural than “many numbers” or “many computations”. “Many” is conceptually simpler that any particular non trivial thing, usually. And then, the collapse needed to avoid the MWI (or the many histories) reintroduce dualism, and asks for a non mechanist theory of mind, which nobody has found yet, except for the usual fairy tales.
