Distributing (trucking, rent and employees at grocery stores, etc) the potatoes costs more than growing them. Even if they are available for free at the farm, the market price in the city cannot go below the cost of distribution without grocery stores and shipping companies working for free, which they have no reason to do. These are already some of the lowest-margin businesses out there.

In this case, it seems that Berliner Morgenpost and Ecosia are doing shipping and distribution for free, for PR reasons or maybe as some kind of charitable volunteering project. It's nice of them to volunteer their time, but it seems strange to talk about “a story about the absurdities of our food system”. Are they saying that it is absurd that a newspaper doesn't permanently turn into a money-losing grocery distributor?
