Well, if the laws of the universe were such that it were unlikely but not impossible for life to form, MWI would take care of the rest, yes.
BUT, if you combine MWI with something that sets the force laws and particle zoo of the later universe as an aspect of quantum state, then MWI helps a lot—instead of getting only one, it makes ALL† of those laws real.
† or in case of precise interference that completely forces certain sets of laws to have a perfectly zero component, nearly all. Or if half of them end up having a precisely zero component due to some symmetry, then, the other half of these rule-sets… etc. Considering the high-dimensional messiness of these proto-universe-theories, large swaths being nodal (having zero wavefunction) seems unlikely.
