I accept Benthamite's criticism as valid. It may not be obvious from the text, but in my mind I was definitely equivocating.

If we can't use preference to determine ethical utility, it makes ethical utilitarianism a lot harder, but that might be something we have to live with. I don't remember very much about Coherent Extrapolated Volition, but my vague memories say it makes that a lot harder too.

I observe that you might have caught this mistake earlier via this heuristic: "Using the phrase "by definition", anywhere outside of math, is among the most alarming signals of flawed argument I've ever found. It's right up there with "Hitler", "God", "absolutely certain" and "can't prove that"." I should probably rewrite "math" as "pure math" just to make this clearer.
