You can undergo training to improve function during hypoxic events and some people are naturally better at dealing with it, but that doesn't mean the general population will have the same experience, so I don't think removing this vital tool for aircraft safety is a good call due to a single incident (let me know if you have a reference on that as I'm very curious).
It would make more sense to determine why the incident occurred and modify the design of the oxygen generators to avoid that scenario in the future, which is what I assumed happened.
