Come on. This is not true.

The whole supply chain is guaranteed (and related companies allowed to work).

Some first hand detail would be greatly appreciated.

What I heard is that roads have checkpoints on them, but aren't closed for necessary trips, which would include food transport. A solo operator of a vehicle driving food to a warehouse or grocery store isn't a big infection risk, especially with appropriate precautions being taken like social distancing, wearing masks, washing hands frequently, etc.

The food production aspect though is more problematic; it can involved larger groups of people and more human contact.

Yeah, there may be one more delivery to the typical store before the end, but without workers, warehouses will empty, and without an economy, generally everything will collapse.

Economies aren't just playthings for little pieces of multicolored paper -- they're the process by which we live a life different from that of a wild animal.

Life without an economy would be smelly, brutal, and short.

Personally, I pray that the US won't try this idiocy, and further pray that people won't stand for it if they try.

I don't think it'll get that bad in Italy. It wouldn't make sense to allow that to happen, as the cure would be worse than the disease. China has managed somehow.

There is no way to know what actually happened in China, due the way they control information.
