Remember that time is just one arbitrary relationship between universes -
and I am inclined to think that the separate universes themselves are also
in the eye of the beholder. Of course, like any 'laws of physics', these
relationships are immutable form our perspective because of WAP. In this
infinite, homogenous jumble that it the 'multiverse', does it make sense to
say that anything exists, let alone discuss measure?

Measure, as a concept, requires the idea of orderly progression through a
sequence of universes, and this is not a fundamental property of the
multiverse.
