I can't get past the paywall, but I'd be curious to know what his solution to the violation of the Bell inequality is.
> We have to suppose that the whole universe, and literally everything there is in it, is collectively a chaotic system evolving precisely on some cosmic fractal geometry. "
I guess one way of trying to make it make sense is that he believes in global hidden variables (non-locality), which reduces physics to "things are exactly this kind of weird because all the complexity of the universe is encoded in one giant number present at the big bang that is available to every particle forever.

Models that violate Bell's theorem are in fact simple to construct. Everyone agrees that superdeterminism can evade Bell's theorem, the key is making this evasion as plausible or more plausible than accepting many worlds or the absence of counterfactual definiteness.
Given so little effort has been expended in this direction because of incorrect assumptions of superdeterminism, it's not surprising that these models are still rudimentary proofs of concept, but the notion that Bells' theorem is some insurmountable obstacle is just incorrect.
