Actually, I didn't notice your "slip up". I interpreted you correctly
as referring to a cubic volume 10^100 planck units on a side.

What I was asking is why you think "time-area" should be proportional
to length. I can't see any reasoning as to what it should be
proportional to.

Indeed in the multiverse there is no net change in
information. However, you are making a fundamental mistake in assuming
information is additive. For every bit gained in a world due to
decoherence, the rest of the Multiverse gains another bit.
