You can't eat insurance money.

We are lucky to live in a age of a dramatic global decline in famine, but a large scale war or natural disaster could potentially unravel this progress in a devastating way.

Subsidies can do preventative tasks that insurance cannot -- like securing additional capacity of food stores and farm land that farmers wouldn't normally do unless they were being paid to do so.

True, but the US gov't stockpiles grain, oil and other things for those kind of events. I don't see how subsidies help in those scenarios either.

Yes, but much like the PPE stockpile, those are only a stopgap measure and aren't really enough to be a comprehensive solution on their own.
