I consider there to be relative determinism, there is also a difference between free will and freedom, you can at least possess free will and experience cognitive or psychological freedom even if this constitutes the limits or boundary of your freedom.
Learning the difference between free will and freedom is one of the major developmental tasks of any human being, at all the major milestones of human maturation individuals test the boundaries of their freedom, against parental authority, against other sorts of authority which can place limits upon freedom and autonomy.
In a certain sense we only experience absolute freedom when we are sleeping, when we are dreaming, and its not for nothing that Freud et al have suggested that this is the royal road to the unconscious, correspondence from the unconscious self etc. because the unconscious is that which is not perceived, outside the realm of human perception. Although expanding the sphere of freedom individually and collectively involves as a prerequisite making the unconsicous conscious if this is the case.
There is a practical value I think in human consciousness and expanding the spheres of personal and social freedom. Perhaps this is a different question to what you are discussing because I think that perhaps you are suggesting that if we are subject to determinism is beyond perception and cant ever be perceived.
