Make it easy for the corpos. Criminalize destroyed food. The financial disincentive needs to be very punitive like some percentage revenue first offense. Then jail time for execs and boards. Those companies may need to hire community coordinators to deal with the near expiring foodstuffs to avoid the criminal liability. Capitalists might assume people would stop buying food and just wait for it all to be near expiring, but the reality is, those with means will take the convenience of a purchase over a long, uncertain wait, potentially queuing hours or even the night before the food banks would open. It might depress prices as they get desperate to trade some of the remaining margin before being required to give it away. Oh no, what will we do if the rich people are slightly less rich!
