It seems to me pretty obvious: in counterfactual world where humans don’t get the answer from the first Oracle, humans say “what the heck” and build a working Oracle that gives answers.
Edit: the trick is in the difference between “this Oracle doesn’t give answer” and “all Oracles don’t give answer”. The first scenario described in this comment, the second scenario requires something like logical counterfactuals.
The idea would be to consider a scenario in which it is something like a law of nature that the predictions of oracles can never be read, in just the same way that the authors are considering a scenario in which it is something like a law of nature that oracles do not and cannot exist.

Hello,
The idea would be to consider a scenario in which it is something like a law of nature that the predictions of oracles can never be read, in just the same way that the authors are considering a scenario in which it is something like a law of nature that oracles do not and cannot exist.
