I do consider free will to be an illusion! But making that argument is far from the slam-dunk that the OP implied, even in the face of quantum mechanics. I don't believe in superdeterminism either. The problem with SD is that it requires all of the information about all future events to reside somewhere now, and there is no known place in the universe where it could be hiding.

BTW, I also believe that it is a defensible position to say that the moon does not exist, but again, this is not an easy argument to make. See:

There's a lot more where that came from if you're interested.
