I don’t have a particularly good understanding of population ethics and I haven’t read Broome (2005) yet, so I could be off base here. But it seems to me that when GiveWell recommends AMF as a top charity, this requires claiming that AMF is in principle comparable to other charities, which requires completeness (or, at least, completeness over the set of charities being compared).
I could also argue that rejecting completeness seems borderline nonsensical, but that’s more complicated to argue, and I don’t really have anything original to contribute on the subject.
