It is, actually. The Born rule gives probabilities that are
incompatible with every outcoming occurring on every trial. If every
outcome always occurs you are led to statements such as "This low
probability outcome is certain to occur", which is nonsense. If
something is certain to occur, it has probability one, but the Born
rule never gives unit probability to a single outcome from the set.
The probability of 1 here is what you get when you consider the entire
multiverse, but this is not the probability that one measures in
experiments to which the Born rule refers to. This probability is
contained in the statistics of the outcome of many experiments, and this
exists in a physical form accessible to the observer. So, if 100 spin
measurements experiments have been done then the outcomes of these exist
in each sector in the form of a physical record.
