Huh? Why?
Shouldn't it be the opposite?
As much as I have a personal will, I will continue to will the same thing if we replay the situation -- all other things being exactly the same.
I don't chose something at random. I express who I am, based on my life story in space time.
To make a light example, if I'm a person who prefers Big Macs over Chinese, I will pick a Bic Mac if I'm asked to make such a decision, no matter how many times we rewind and replay the universe state.
Free will is not about me suddenly picking some random alternative. How would that ever express who I am (and thus, my, _my_ personal will?).
What's "free" about this free will since its inexorably tied to my space-time history? Well, it's exactly the fact that it's my space-time history, and can't be altered based on some external factor.
It's not "free" as in arbitrarily changeable, but free as in "expressing me and only me" (that is: my space-time history who made me what I am).
