This. Truly sustainable practices require a considerably lower profit margin per acre, thereby forcing the parasitical middlemen to give farmers more without utterly hosing the consumer for all that they are worth.

And some overproduction is required to handle lean years. While you cannot keep fruit fresh for years, you can convert it into almost-analogous forms like flash-frozen in the field, within minutes of being picked, such that it can bridge the gap in lean years.

So there always will be some overproduction and some waste in the system, but not to the point where it needs to be intentionally made inedible so it cannot be given away, in order to create artificial scarcity to sustain market prices.
