This is a very relevant point. The more we're able to reflect upon ourselves, the more we can overcome all sorts of powers that normally constrain our 'free will'.

Logically you can argue that there is no difference in levels of constraint when we make the distinction between free or not-free, but that way of looking at it is seriously flawed. You miss out on another dimension when you don't take the several degrees of constraint in consideration and limit yourself to a one-dimensional yes-no picture.
