But this is talking about the innate vs. the adaptive immune system. I am not a medical professional, but it seems like the innate system is either maladapted or not. In any case, I don't think it's fair to assume that your "common sense" overrides my skepticism.

There are likely biological pros and cons between innate and adaptive, such that using the innate response for everything is not desirable.

The innate response is less targeted, less effective, and causes potentially damaging effects like inflammation. The adaptive response is more targeted and more effective, with the tradeoff that it needs to be learnt.
