You're not. The "problems" this article suggests for MWI are actually only problems for people who don't fully understand it. Attempting to count worlds, for example, is a mistake right from the start; perhaps MWI is badly named, but decoherence doesn't produce fully disjoint worlds. They always overlap with their neighbours. For an analogy, trying to count MWI worlds is like trying to measure the length of Norway's coastline. It depends on how you count, but "worlds" also aren't a fundamental building block; it doesn't affect the predictions of the theory.
