this is not as bad as it sounds, people can discover many other sources (also lower cost) of protein. perhaps this leads to decreased meat consumption, not at all a bad thing.
If this was a simple change of preferences due to all the vegan/vegetarian talking points, I could agree with your premise. The thing I wonder about C19 is that what kinds of agricultural processes involve humans ensuring that beans/corn/greens/starches get from the fields into produce aisles and cans? The same reasoning on shutting down production for infection risk applies there as well.
Meat has the shortest shelf life of foods, so any impact on the food supply chain will be felt there first.
US Agriculture as a whole employs 22 million people. Of that, meet production is about 500,000. Fruits, vegetables, and grains take an order of magnitude more hands to make it to the table, so to speak.
