Correct me if I am wrong, but your argument sounds like: "people can decide that there is no free will, thus it exists". I don't see how the conclusion follows from the premise. Surely one might decide that free will does not exist in a universe where it does not?
Perhaps we have alternative definitions of free will. I believe that whenever I (or anyone else) have made a decision, then rewinding time to the exact moment before the decision will only cause me to make the exact same decision again. I find the idea that I might decide otherwise disturbing.
One might argue that quantum randomness could influence decisions, but I would argue that adding true randomness to an otherwise deterministic system does not make it any more 'free', even if the system stops being deterministic.
I would love to hear how you define the'free' in 'free will', and how its existence follows from your argument.
