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.
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.
We are about to have millions unemployed. Any job vacancy will be trivial to fill.
I wouldn't be concerned about the food supply.
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.)
Eventually we'll have a vaccine, and life can go back to normal (if we want). The main problem in the interim is keeping everybody from freaking out because the before-times social constructions weren't really set up for a global pandemic. But we can fix that if we want.
