If I understand what you are talking about, I have expressed disagreement with it a couple of times. My disagreement has to do with the values expressed by a coalition (which will be some kind of bargained composite of the values of the individual members of that coalition).

But then when the membership in that coalition changes, the 'deal' must be renegotiated, and the coalition's values are no longer perfectly persistent - nor should they be.

This is not just a technical quibble. The CEV of mankind is a composite value representing a coalition with a changing membership.
