However, I think people grossly overestimate the degree to which this state of affairs is static. If the supply chain shows itself to be vulnerable, economies often adjust quite easily. Even when it's not "easy", like natural gas in Europe post-2022, it's still very much doable without too much hullabaloo and frozen seniors. Point being: if it no longer makes sense to import 38% of blood from the US or whatever, it'll be imported from elsewhere or made locally, and that's pretty much the whole story. This is true of most goods and services, though not all.
