Superdeterminism is even weirder than that though. Why would the universe conspire to make sure that I picked my observation angle just right to maintain Bell's inequality? If you use the outcome of a celestial event to determine the angle, then you've got an absolute enormous conspiracy just to make sure that Bell's inequality isn't violated. It's deeply weird.
If free will were an illusion, it wouldn't make sense to try to convince anybody of it. IOW, if you're right, your comment is useless :-)
But I'd understand why you had to write that anyway :-P
I always thought the opposite. It seems things like non-determinism and retrocausality made free will more physically coherent instead of less coherent. It is the strictly deterministic universe of Newton that makes free will illusive.
