The "very essence" of being a boss is knocking out obstacles for the people under you. That is what a boss actually does, not tell people what to do. Sure, a boss translates vague prioritization from above to meaningful and actionable items for his/her team to work through, but the only "power" a boss has is the ability to absorb shit so the people under him/her don't have to.
The boss also has a boss, who has a boss, and so on and so on, up to the CEO, who has a boss (the board and/or shareholders). No one gets to "force subordinates to submit" to anyone, at least not for very long.
