We don't have zero free will.
Autonomy is a sliding scale. We are image bearers of god. We have more autonomy than all of the other beings in Crestion (the animal kingdom). And yet we are mortal beings and have a certain nature that drives us to sin. We are free to sin (rebel from God) in any way that we like.
Compared to God, no we don't have free will, obviously. But we do have the autonomy to choose and act and we are real conscious beings that God created.
