How does a director-screenwriter EARN full creative control? Is this even possible in a collaborative environment like a filmmaking setting?

Alright so the scenario is that you're a director-screenwriter and you've landed a producer and a team with a clear vision in mind. This is probably the ideal scenario for almost everybody in this sub. However, I just realized that in such a collaborative field, EVERYONE on the team is going to have their OWN vision that they'd want to see on screen. So how exactly does the director have everyone collaborate and make the film production run like clockwork? How do you take everyone's input and opinions without compromising your own vision? How do you deal with adamant members of the team? (I know big stars have a lot of demands as to how they're shown on screen and often times this derails the film). I've heard Tarantino brings his exact vision onscreen, I want to know how to do this while having to collaborate with hundreds if not thousands of people. What do y'all think?
