But there are also costs considered: no flexibility, thus no way to hedge risk. Think weather, plagues and diseases, funghi whatever: If you single crop is vulnerable, now all of it is affected. The use of pesticides and fertiliser is also not free, and monocultures need a lot more of that. Furthermore the giant tractors needed for monoculture tend to damage the soil they drive on, and require the ground water table to be fairly low.

Certainly the logistical challenge of multiple small harvests of varying products is there, but this is definitely more manageable with robots and computers than without.

And for a small close to population centers, if they can supply multiple kinds of produce reliably, they might be able to make orders of magnitude more money on the local market than on the commodities market.
