No. It changes the problem to the question of why there are
preferred
bases.

Who chose Alive and Dead, or Awake and Sleeping for the S. cat?
Wasn't it the observer? Since they had other choices, my claim
stands. AG
Everett showed explicitly that the relative states, and their relative
statistics does not depend on the choice of the bases.
Something quite similar occur already in arithmetic, with a much
general notion of "base”.
But he didn't explain why observations were only possible in some bases.
