I don't think there is anything vague about this. It's obvious management is responsible for setting attainable goals and priorization, and making sure 'things work'. The latter part is the hardest, I suppose. That can turn into micromanagement. Not focusing on the prior items is negligence, so yeah, in principle I agree with you that no-mamagement is worse ethically. Although there can be situations where the team actually does know the best and the managerial role focuses on non-project related issues
