That you are embodied and act purposefully and intentionally, that you have certain drives associated with the body and desires formed by your own ideas of satisfaction, and that these overlap and you must choose between the, just as you can choose to follow the dictates of your drives or not, all this as immediately a component of your way of being is all the meaning that needs to be given to 'free will'. Anything that attempts to dissolve this immediacy in the name of neuro-physical causality or other metaphysical notions, such as 'simulation', can only have the significance of a conspiracy theory. If you think there is no free will then you think too much.
