Without something like mangled worlds, one can be tempted by an objective collapse view, as that at least gives a coherent account of the Born rule.
Does it really account for it in the sense of explain it? I don’t think so. I think it merely says that the collapsing occurs in accordance with the Born rule. But we can also simply say that many-worlds is true and the history of our fragment of the multiverse is consistent with the Born rule. Admittedly, this doesn’t explain why we happen to live in such a fragment but merely asserts that we do, but similarly, the collapse view does not (as far as I know) explain why the collapse occurs in the frequencies it does but merely asserts that it does.
