Apart from back office, management, and some sectors of service providers (those that work predominantly in an office with a laptop), this is simply not possible. I suppose the WFH bunch are only a potion of the workforce.
By definition, to produce/work, people need to be at production facilities and work with tools (could be other humans). Unless their 'home' is the production facility (sole contributor, freelancer, etc.), this is simply not achievable. Which is why factories and construction sites and law enforcement and etc. cannot shutdown. It is simply not doable. Still, accounting, legal, customer service, IT, etc. these can WFH, to a certain extend, but as you can tell they produce services mostly, not goods. I might also add that they stand on top of the foundation of physical goods production, not unlike the dependence of carnivore on herbivore.
We are already seeing physical retail stores in malls packed up and left, ignoring rental contracts. Even F&B outlets are impacted (especially cafes), it seems takeout orders are simply not enough to cover. They either sell the business, or simply liquidate the assets and close down. Guess what happens to the accountants of these businesses? Given the lower amount of traffic and economic activities, demand decreases so will production (as per your mention), but there is always a delay between production and consumption.
We all know that Q420 is gonna get another hit if the Order gets an extension. It is just deflationary and detrimental. Hopefully this doesn't go beyond the point of no return.
Apparently the fear of an entity can cause much havoc than the entity itself.
By the way, beautiful music that. The former.
