For most of history humanity grew it's food locally, it depended on local items, got killed by local actors as you state. Each locality was its own anti-fragile little kingdom.
But this is no longer true and this is something we saw during covid. If a factory blows up in Tokyo that makes the live saving medicine/device that you depend on to keep surviving, it's no different for you than your city catching on fire. If all the crops die in some foreign place and you live in a food importing country, trouble is coming. If a war is blowing up ships then supplies you need for your business may not show up any more and bankruptcy could be on the menu.

We live in a fragile black swan dominated world.
