Only in the case epidemics or natural disasters. And even then I would argue that's nit the case. E.g. there was a major accident in a Chinese chemical park last year, it closed down for the majority of the year. This park manufactured the raw materials for stuff like car lights, the glasses of them. It also was the only source. Did anybody outside the industry suffer any results? No, because supply chains actually adopt pretty well to stuff like that. What would happen so, if everything is in one place is higher costs off-crisis, you wouldn't survive economically to see a crisis that way.

Recovery is key, so. And that is where we will see which companies did their jobs supply chain wise and which didn't.
