The economy cannot be modelled as a linear system; it is a pseudo-chaotic system.

If one poorly-chosen element is labelled as a "non-essential business", it can cause all the other metaphorical Jenga blocks to collapse.

Yeah, this is just like the WHO announcing "no evidence" antibodies provide some immunity. It just means no one has done a scientific study of how to collapse the food supply on a massive scale. These sorts of "everything is peachy neat keeno" claims are like Fauci saying the "risk to the US is low" back in February. There is a nontrivial risk we are headed toward food shortages. We should get back in a safer, more well understood configuration for food production and distribution.
