CEV of humanity is certainly desirable! If you CEV me, I in turn implement some kind of CEV-of-humanity in a way that doesn’t particularly privilege myself. But that’s downstream of one’s values and of decision theory.
Your goal as an agent is to maximize your utility function — and it just so happens that your utility function, as you endorse it in CEV, consists of maximizing everyone’s CEV in some way.
Think not “cosmopolitanism vs my-utility-function” but “cosmopolitanism, as entailed by my utility function”.
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.

(see also my post surprise! you want what you want)
It egoism is incoherent,and altruism coherent, I suppose that would follow...but it’s a big if. Where is it proven?

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.
