For all practical purposes, it does not matter in the slightest if we actually have free will - who cares what's happening on the quantum level? We can choose (pun intended) to live as if we had free will or as if we didn't - that is what matters. It's just the same as god - it's not that important for our lives if god is real or not (also we cannot ever know) but what matters is if we choose to live as if it exists, however metaphorical or even atheistic our vision of that is. Do we have an ideal we can strive for but can never fully achieve? That is kinda what god is. If we believe we can get better by making the right choices - we have free will, or as close to it as it really matters.
