Simple. People shouldn't profit from misery.
Profit is not good, if your business is basically black marketing. That is, removing a product from its normal retail chain just so that you create a shortage and then sell with a profit due to the shortage created by you.
And with medical supplies, we need to make sure that all those, who are in desperate need, get the needed supplies.
I cannot think of a better thing that I would want people to profit from, than the act of reducing misery around the world.
The people who reduce misery are the ones most deserving of profits and reward.
