It seems to me that as soon as we talk about measure, it is equivalent
to talking about one (physical!) universe. This is similar to your
George Levy's taking the ratio of the lengths of two line segments.
You don't need a multiverse to do that. I think that talking of
measure in the multiverse is taking a common sense thing in a single
universe and (erroneously) trying to make it make sense in the
multiverse. I don't think it works. So yes I'm ignoring something
that doesn't work, in my view. I brought up the problem of the
additional 10^100 copies, but your bringing up the word "measure"
doesn't solve it. The reason why you don't buy lottery tickets could
just as easily be explained in a single universe.
