Yes, and that’s exactly the problem—Gleason’s theorem doesn’t apply to
two-dimensional Hilbert spaces, which means it doesn’t universally
derive the Born rule. So if MWI fails for not deriving the Born rule,
then standard QM faces the same issue unless you introduce additional
postulates.
Branch counting doesn’t work, but my example isn’t branch
counting—it’s asymmetric duplication, where observer distribution
follows measure,
Observer distribution is only one observer per branch; the observers
can't see each other. So N observers implies N branches. It's
mathematically equivalent to branch counting.
