The problem with people's adulation for this mythical Sparta is that it includes ideas about causation (they were strong because they were monomaniacally focused on war!) and morality (military strength is a more important merit for a society than economic success or cultural output!) drawn from the real Sparta. ie people who want to reproduce the mythical Sparta often advocate the social structure of the real Sparta, thinking it will lead to those mythical benefits. And instead it leads to monstrosity.
