I think it's the opposite. You need a "God of the gaps" in the form of a "person" (actually a collection of phenomena. + the phenomena of identification with these) to explain free will and agency, which defies experimental evidence.
The comment that superdeterminism requires a higher-order determinism, which itself requires a yet-higher-order determinism... I think you're confusing it with a causal mindset. If the universe is effectively a recording, why does it need any ultimate cause? Causal thinking would only make sense from a perspective within that recording.
Of course we want to know "why is any of this here?" But what if the ultimate question doesn't actually have an answer?
