While I think you make some fair points, I also don't hear an argument against the belief in free will :)
For what it's worth, my argument was never that free will must be true, so I didn't fall for the argument from consequence fallacy. I merely said it's better that we should believe in it for our own good. There's a recognition of the limits of the argument in there.
But even though we recognise such limits exist, doesn't mean we should come to the conclusion that free will itself doesn't exist. I'm also not limiting my argument to rational ones, as I cite several empirical studies that also conclude that a belief in free will is better for us.
So yeah, it's fair to point out some limitations, but I wouldn't say that any of these arguments are divine or beyond examination. Please do examine them! But until there is a convincing argument against the belief in free will (rational or otherwise), I'll stick with my conviction that believing in it is indeed better for us.
