> why is my outcome not worse for believing I don't have free will?
You still don't get it. Your brain is doing the thing that I call "making choices", but which I called "causal processes" because you have trouble with words like "choices", whether you believe in free will or not. Those causal processes in your brain have a significant effect on your outcomes, whether you believe in free will or not. And how much of an effect the causal processes in your brain have on your outcomes, as compared with the effect that causal processes in other people's brains have on your outcomes, which is the thing I have said is important, has little or nothing to do directly with whether you or anyone else "believes in free will". It does have to do with whether you and other people respect other people's right to make choices, which I have also said is important.
But the has nothing to do with the idea that one has free will, only that I exhibit behavior that allows you to pursue your own desires, I.E I'm not actively harming you or putting you into prison. Redefine what free will means all you want, it doesn't make your arguments any more true.
