Supermarkets rely on just in time deliveries. We learnt during COVID that even a slight delay can cause problems. Enough people then panic buy to snowball it.

It would take remarkably few road closures to leave towns isolated from supply chains. A 72 hour buffer is very useful in those cases. Even if it's just to relieve short term pressure on those supply chains when they reconnect.
