What about a single, infinite world in which everything is
duplicated to an arbitrary level of detail, including the
Earth and its inhabitants, an infinite number of times? Is
the bizarreness of this idea an argument for a finite
world, ending perhaps at the limit of what we can see?

FWIW, in my view we live in huge, but finite, expanding
hypersphere, meaning in any direction, if go far enough, you
return to your starting position. Many cosmologists say it's
flat and thus infinite; not asymptotically flat and therefore
spatially finite. Measurements cannot distinguish the two
possibilities. I don't buy the former since they also concede
it is finite in age. A Multiverse might exist, and that would
likely be infinite in space and time, with erupting BB
universes, some like ours, most definitely not. Like I said,
FWIW. AG
OK, but is the *strangeness* of a multiverse with multiple copies
of everything *in itself* an argument against it?

FWIW, I don't buy the claim that an infinite multiverse implies
infinite copies of everything. Has anyone proved that? AG
I think it depends on assumptions about what kind of infinities are
involved. Is spacetime a continuum? Is the universe spacially finite?
Does the Planck scale imply the universe has only countably many
possibilities? Nobody proves anything in science; and in this case it's
hard to get any empirical evidence.
