As you can see from the sentence before the one you quoted, I didn't forget about it.
I agree there's a lot of complexity there. But it's still a relatively small slice of the population. A friend is a farmer; she's just carrying ahead farming. Compared with urban life, she's been "socially distancing" for years. For the more dense parts of the chain, we need to take other infection-prevention measures. But food production is already pretty good at keeping things clean, and the rest we can work on.
It's worth remembering how efficient our modern food systems have become that less than 3 out of 100 people are enough to work them.
That said, it wouldn't hurt anything to start a "victory garden", it's the right time of year. https://en.wikipedia.org/wiki/Victory_garden (but that's a good idea anyway, orthogonal to the virus.)
Don’t forget about food. There’s a lot of complexity and people involved in getting food from a farm to your local restaurants and grocery stores.
If it gets really bad and even a fraction of people in these industries stop working, stay-at-home life might get a lot less comfortable.
