Here's the thing: free will is the capacity to act according to your own nature-- nobody is ever going to make a decision that is not in their own nature. So for all functional purposes, everything you do if there's no free will is probably exactly what you would do if you HAD free will.
Did I freely choose among the candies to arrive at my Smarties purchase, or did some long causal chain back to the Big Bang lead to me having life experiences and eventually hormonal or neurological states that made it inevitable that I would choose Smarties?
My answer-- who gives a shit? I AM my experiences, my hormones and my neurological state, and there's no other basis on which I would want to make decisions anyway.
