It egoism is incoherent,and altruism coherent, I suppose that would follow...but it’s a big if. Where is it proven?
Oh, egoism is totally coherent. I’m just saying that your values can be egoist, or they can be cosmopolitan, or a mixture of they two. But (a version of) cosmopolitanism is a contents of a person’s values, not a standalone objective thing.
How does that help in practice?
I’m not sure what you mean? I’m just describing what those concepts are and how I think they fit together in the territory, not prescribing anything.
