I mean, that's part of the problem with modern supply chains in general: they've been deliberately consolidating (to ensure those at the top get maximum profits) and stripping any redundancy or buffer to the bone (to ensure that no money is ever spent on something that's not immediately relevant to making more profit). This is a big part of why the supply chain shocks in COVID, and the Ever Given blocking the Suez, were so very disruptive.
