I short-changed my argument. I should've said, "The reason why you don't
buy lottery tickets can only be explained in a single universe."
If you don't accept a measure on the entire multiverse, then you're not
going to have any solution to what on this list is usually called the "white
rabbit problem", explaining why you don't expect to see weird events like
talking white rabbits or Harry Potter style magic or 300 successive lottery
wins. After all, there should be possible worlds within the multiverse where
everything up to today is just the same as in a "normal" universe where the
laws of nature stay stable, but after that point the probabilities of
strange white-rabbit-style events radically increase. Since your experience
up to the present is compatible with either type of universe, unless you are
willing to say that white rabbit universes have a lower absolute measure
than stable-laws-of-nature universes, you have no justification for
expecting that you are unlikely to experience such events in your future.
