The thing is Starfleet isn't a military organization and never was supposed to be. The ranks and command structure may emulate it but is more ceremonial/designed to give a chain of command than it is supposed to be anything to do with an extension of the military.
*ahem* BULLSHIT *ahem*
A ship wouldn't last five minutes with that attitude, nor would any other chain of command. It's not ceremonial, it's THE COMMAND STRUCTURE. Orders are not optional and are not open to debate.
See, for instance, the scene in TMP where Kirk is about to ream Decker for countermanding his phaser order. If Decker hadn't had a damn good reason he'd have found his ass in the brig for the rest of the trip.
