Ok, if you insist :)

I think the above are two disparate arguments. It is simpler by Occam to
assume that there should be many observers rather than only one (similar
argument to favouring the multiverse over only one big-bang). Once you admit
the possibility of one observer, it takes extra argument to say why there
should be *only* one.

But we expect the universe to be old for cosmological reasons (takes stars a
long time to cook up the needed elements, observer take a long time to
evolve). Simplicity does not seem to be a factor here. A big universe does
not seem much simpler either.
