utility is not just an ordering, it also has affine structure (relative intervals are preserved) because of preferences over lotteries.

Only among ideal agents, not among apes.

That is one version of the statement that human utility isn't well defined, i.e., cousin_it's point.

Hmm. It seems to me that your statement is directly contrary to cousin_it's; if X isn't well-defined, X can't have an affine structure.

if X isn't well-defined, X can't have an affine structure.

Yes, and it seems you agree that human utility doesn't have an affine structure.
