Well, if you know your local farmers and buy from them regularly, it doesn't look great if they jack their prices up unnecessarily. They also know that they're competing against the perception that local food is more expensive. In normal times, factory farms can always undercut their prices, so it would make sense for them to use the current situation as an opportunity to get more people to start buying local (due to the prices!) and hope that they will continue to buy local once the prices invert again (due to the quality).
