I don’t think this is necessarily true. Delegation is the name of the game in any large organization - managers exist to sift down tasks to a doer. You can’t delegate many kinds of tasks by inspiring people. You can generally only inspire people into things they want to do and find interesting anyway but the unfortunate truth is that there is a lot of boring/annoying/not fun stuff that needs to be done and it can’t all be done by the CEO alone.
