As far as I can tell it's a bit of a "these are the tools we have" kind of thing. The institutions that could do effective targeted supply-stimulating policymaking are hobbled if not hamstrung right now, while central banks are less so but only have blunt macro tools to work with. There's not really much solution other than "people have to care about concrete policy, or at least specifically supply."
