The interesting question is what are the myriad factors that contribute to the state of a system at a specific time. From hormones to shoe color to genes to what you ate for breakfast to how you were raised.
Like I said before the more interesting questions are about the interaction of a system with the rest of the world such as what brought the system to a state that it makes a certain choice, what are the dynamics of that state, how might that state change based on different stimuli, can we nail down what exactly is going on in all the relevant parts of the system at a given time etc and if not how close can we get.
I do wish the ever increasing stigma around it in serious conversations would hurry up and increase so we could stop wasting our time with it though ;)
Free will as its commonly understood is an entirely religious concept and has little/no utility in explaining behavior. It is, IMO entirely unrelated to consciousness and a distracting subject that traps people into circular reasoning.
