because we cannot access the parallel worlds where our copies live, and
because even if we could, we can only experience being one person at a time.
When you say "if you believe that everything possible exists" are you
implying that everything possible need NOT exist (thus refuting Tegmark)?
Wouldn't this mean that space-time was not infinite? What hypothesis could
explain finite space-time?
If you believe that everything possible exists, does this not mean that
there exists a universe like ours, only as it will appear 10^100 years in
our future? And that there also exists a universe like ours, only as it
appeared 10^9 years in the past? And that, in all worlds, all possible
events have occurred?
