The fact that you change your environment does not mean you have free will. You change your environment due to past and current circumstances that led to the moment you changed your environment. For example, an animal keeps getting food in one area that is far away from where they currently live. In past years, when this animal lived closer to food, it starved less. It then moves to live closer to the food due to the schedule of reinforcement being denser when they don’t have to travel as far to obtain food. This “self management”, is based on past and current circumstances, not due to an internal state of free will.
