The argument being made is already there in the storyform. For example, in the movie Star Wars the argument is being made that if you trust in something outside of yourself to solve your problems you will succeed and you will feel great about yourself. In the play Hamlet the argument is being made that if you start to accept what you know as true you will perish and fail to overcome personal problems.
This is not an argument, this is a compromise. Dramatica theory sees narrative as a Grand Argument Story. If you’re not looking to make an argument, but rather a compromise, then Dramatica is not for you. This is a basic given of the theory. You don’t have to accept it (that’s what a given is all about), but know that you can’t have it both ways (unless you adore compromise 
)
If you wanted to argue the above you would have to have someone who thinks you only need one and someone who thinks you need both and the one representing both would “win”.
