While this is technically true I don’t think that that means that the many worlds theory is the simplest or the most straightforward. In other areas of science we don’t take our mathematical formalisms to be real. Scientist don’t fret about whether inches exist in the world or that energy is “real”, yet somehow we are led to believe that just trusting in the Schrodinger equation and assuming that it’s “real” leads us to the obvious conclusion that there are many worlds. Now there are other reasons that I like the many worlds interpretation. If you get over the conceptual hurdle of its implications, it’s nice because it doesn’t cause immediate theoretical breakdown based on questions that a precocious child would ask, like “what is an observer?”
