There's a whole school of "Industry X is totally dependent on far flung facility Y" journalism. ("your cellphone depends on coltan from African wars" from a few years back is the worst offender - not that people shouldn't be concerned with such wars but concern should be based on a reasonable lens). That said, the world has experienced quite a few supply chain disruptions in recent years and a big factor is large-scale, highly capitalized enterprises wind-up preferring situations of not producing at all to situations of increasing or continuing production at a lower profit rate for an emergency situation. (I remember covid vaccine production was limited by drug companies unwillingness to invest in new gene printing machines, US hospitals didn't buy US made masks because neither the mask manufacturer would make/accept short-term contracts at temporarily higher prices, etc. We all whine about AMD's unwillingness to compete directly with Nvidia with a Cuda-clone system). Which is say, yes markets generally take risks into account but some amount of fragility seems to be a risk markets are willing to pay.
