This brings up the end of the second approach I mentioned; does it really make sense to talk about an individual experiencing that much (negative) utility? Even if it’s not a ‘more northerly than the north pole’ definitional impossibility, might it be a ‘climb higher than Mount Everest’ physically practical impossibility?
Oops, took so long to write my reply that this post went from having no comments to having a discussion of my main point :-) (But my reply still expands on these points, so I won’t just delete it.)

Short answer: This objection is saying that your utility function should be bounded, which is one of the standard answers, though I think that many people suggesting a bounded utility function were just doing so as a way to fix the problem, rather than arguing from first principles that you really shouldn’t care that much more about the mugger’s threat than about losing five dollars.
