In reality the market isn't a zero sum game. And there isn't a fixed supply of resources. In a crisis scalpers ensure that the customers receive critical goods that may otherwise be unavailable at any price. Not having that option could kill a company just as well. All of the profit money doesn't go to the scalper either, the original manufacturer can sell for higher prices, reallocate resources to make what is most profitable and meet the demands of the market. And there are price gouging laws to limit this activity for essential goods in an emergency.
