I think over the coming weeks, we're going to see just how much of the "essential" part of the economy depends on the "non-essential" part.
For example, a comment in one of these postings on HN was talking about how the manufacture of essential supplies was continuing and robust (even I've made a similar comment some time ago). But... ok... how much of the logistics capacity, the capacity of hauling those essential products from the factory to the final buyer is being impacted? And it's not just trailer cubic feet availability that's at issue... it's are those containers available in the right place at the right time? Greater cubic feet available for essential products in fewer overall containers is still a potential major problem. I have to think that a fair portion of the common carriers are dependent on a mix of "essential" and "non-essential" goods for their business and that some of these common carriers are marginal even during the "good times". Fewer trucks/trains/drivers/etc, mean that getting a truck scheduled to a loading dock on a timely basis is harder, even if available cubic feet for essential goods has risen. If my speculation holds, manufacture of essential goods will be robust, but there will still be shortages at the stores and for buyers simply because shutting down the non-essential has reduced available containers and the bottleneck has shifted to inventory logistics. I can repeat this sort of thing for many different parts of the economy; I went to get a replacement part for a computer keyboard... the company's website said they were closed under county order as a non-essential business.... yet food producers still need to use their computers to ensure they can monitor available shelf-life, etc.
When we see broad pronouncements from politicians and bureaucrats talking about not shutting down essential businesses, I wonder if they appreciate how interconnected the modern economy is and that it doesn't simply break down into "essential" and "non-essential". Perhaps this sort of thing is why I so distrust those that would embrace economic central planning.
