There are some moral intuitions, such as the ‘procreation asymmetry’ (illustrated in the ‘central illustration’ below) that only a person-affecting view can capture.
I don’t think this is exactly true. The procreation asymmetry is also consistent with any form of negative consequentialism. I wouldn’t classify such views as “person-affecting,” since the reason they don’t consider it obligatory to create happy people is that they reject the premise that happiness is intrinsically morally valuable, rather than that they assign special importance to badness-for-someone. These views do still have some of the implications you consider problematic in this post, but they’re not vulnerable to, for example, Parfit’s critiques based on reductionism about personal identity.
