I would say that for someone who accepts liberal ideas (counting most conservatives in western countries), this seems like a very useful argument for convincing them of this: If we always used intuitional morality, we would currently have morality that disagrees with their intuitions (about slavery being wrong, democracy being good, those sorts of things).
Of course, as a rational argument it makes no sense. It just appeals to me because my intuitions are Consequentialist and I want to try to convince others to follow Consequentialism, because it will lead to better outcomes.
