Yes, the supply chains can be disrupted. Of course the governments will make sure that grocery stores, pharmacies and trucks for food delivers will still be open or be able to pass borders. But unforseen events can make it so you local grocery store has close or runs out. I've had people I know infected with the virus and I know even more people who can't come to work, because of some other events, like Kindergardens closing, so they have to stay at home to watch their kids. It's not always as simple as "no more flour", it can be an unforseen event that can hit you hard.
