I'm more interested in whether we address supply-chain and infrastructure fragility. Not for economic reasons, but for overall survival and quality of life issues.

Imagine this sort of thing going on contemporaneously with people fleeing coastal cities due to flooding.

not sure how fragile it is, frankly logistics is very robust (and has been since the middle ages). Even with centralization it survives multiple trade wars at this moment. And it depends a lot on information tech which is also robust.
