Virtue Ethics doesn't seem to describe how Scott Alexander experiences moral decisions. It seems irrelevant to how morality actually works in his case.
If Virtue Ethics is just about using one's "intuitive morality" instead of thinking rationally, then we don't get anywhere. All we can do is habitually do the good that everyone already knows is good. There's no room for improvement and no way to solve dilemmas.
Virtue Ethics, on the other hand, cannot even attempt to solve any moral dilemmas.
