Oh, sure -- maybe for some of them. But anyone who thinks this isn't going to devastate many, many businesses is delusional.
Case in point ...
Farms can operate. Food producers can operate. If the restaurants that buy from the food producers aren't open, how much business can they do (hence the stories you're reading about farmers destroying their commodities because they can't sell them).
The vendor I use for my printing is closed. I am open (I never closed, even though I'm supposedly a "non-essential" business). I need a print job done. If I can't get the printing job done professionally I'm either going to do it myself or have it done out of state and shipped here via FedEx or UPS. Do you think that printing business is going to have a full base of customers when it is permitted to open?
Opening businesses "not all uniformly" ignores the essential relationships between different types of businesses. A governor whose staff sits down and identifies "essential" and "non-essential" businesses using a NAICS industry code is an ignoramus, and is a major threat to the well-being of the constituents in that state.
There is truth in much of what you say but still people forget and they do so quickly in the absence of anything close to what the “authorities” were projecting.
Sadly we are a nation of sheep and once people start going about their business in force others will join them.
As for business failures? Sure there will be some and that is too bad. However good business sense dictates having enough capital to sustain a business interruption of a limited nature.
AS for farmers killing livestock, I’m not a farmer but I don’t know why it was necessary to kill them rather than keep them alive a while longer. Probably has something to do with the cost of feed etc but as I said I am not a Farmer.
