>To a very good approximation, the marginal impact of any hoarders on the scarcity of a product is zero.
This is pure ideology. Do you have any evidence that a single person buying 10,000 masks from every hardware store in an entire state has no marginal impact on the scarcity of a product? Basic math would suggest this is not the case.
He bought most of the masks from a single liquidation company a month ago, and he bought the hand sanitizer from some stores in Kentucky & Tennessee, but not in large enough quantities to cause shortages there. He definitely didn't buy from every hardware store in the state. Not even close.
