I would be surprised if Eliezer believed (1) or (2), as distinct from believing that CEV[X] is the most viably actionable approximation of morality[X] (using your terminology) we’ve come up with thus far.
I didn’t intend to distinguish that finely.
I’m not really sure what you mean by (4).
(4) is intended to mean that if we alter humans to have a different value system tomorrow, we would also be changing what we mean (today) by “morality”. It’s the negation of the assertion that moral terms are rigid designators, and is what Eliezer is arguing against in No License To Be Human.

Ah, gotcha. OK, thanks for clarifying.
