One risk is that our systems are now extremely efficient, and one aspect of efficiency is that it tends to eliminate “unnecessary” buffers and stockpiles. Just-in-time manufacturing pulls supplies in response to demand. The global food supply chain still has buffers and stockpiles (e.g. grain bins) due to the seasonality of growing, but if hydroponics becomes the dominant method of agriculture (say, in a world with a more chaotic climate that needs to be kept at bay by greenhouses), then highly efficient farmers could optimize out all of their resiliency.
