A good point.
Another point can be: A l-Daemon in this universe must know even about itself, being a part of the whole, creating a loop?
in ANY case, reality cannot do a replay. we cannot have twice the same universal configuration/conditions and compare evolution/results, so we don't know (for sure) if reality is ruled by a full deep determinism (quite probable, IMHO).
Who know if apparent 'randomness' of physics world is the ignorance of deeper causes. (J.L.Borges docet)
And maybe free-will for a finite system (a human being) is real/significative inside the boundaries of the complexity arising even in a full deterministic reality. More complex the system, more far-from-predictable the dynamics, even a fully causal/deterministic one. Being no super-predictor in pratice (and in theory), free-will is a condition quite significative. Our finite-nature grand it in a infinite universe..
The article's argument is that we can't build a computer or a brain or something that can perfectly predict the state of the universe (given an earlier state), since that computer or brain must itself be part of the physical universe. But that's specious reasoning. The question is whether the laws of physics themselves predict to the point that free will doesn't exist. Whether we can reproduce that in another mechanism is completely irrelevant.
And because of that hole, this entire argument fails.
