The argument will always be that “oversight could have prevented X” but we need to emphasize what I highlighted; could is not the same as automatically would and with no tradeoff/downside.
We also need to emphasize “what kind of oversight? Underwriters Laboratory-style oversight? or government oversight?” noting that the later has its own incentives, and creates its own problems, as Robert Higgs goes into at length here; this kind of oversight kills more people than it saves.
