I think that there is often a mistaken conflation of the multiverse with Everett's many-worlds interpretation of QM. The latter does indeed seem to imply that (in some poorly defined sense) all possible outcomes exist. But most versions of the multiverse are based on completely different ideas.
Well I've never been clear on that aspect. But if it's as you say then ISTM the multiverse doesn't really help with the issue of why all the constants in our universe appear fine-tuned. Because it just kicks it further down the road: considering the infinity of multiverses that could not harbour life, what good fortune this is the one that exists.

NB: This isn't a religious argument. And I'm on the fence of whether I think it's even a meaningful question
