I have no idea how resilient the food supply lines are going to be through all of this, but it is true that people not being able to find meat would make them freak out more than a little bit.
Not justifying Trump going about doing everything the worst way, but ensuring an adequate food supply is not in itself a crazy goal. And again, no of course I'm not justifying what will be "lol go back to work and bring your own PPE and try not to die mmmkay."
