That's the kicker, isn't it? Their output will be lower than an industrial farm of equal size. However, the quality of product will be higher (this is an assumption btw), and they will be able to charge more for the product for being grown organically and using less pesticides and the like. There may also be subsidies involved, depending on the location.
But profit should not be the goal. It's necessary, but it shouldn't be the target.
I'm not sure it is a goal. It certainly hasn't been the goal of most farmers since I started farming, and I am not sure it ever was. The goal of most farmers is to build wealth. Much like tech startups, they are willing to forego profit in the name of growth. Asset rich, cash poor is the name of farming.
> It's necessary
It's more or less necessary for a farmer to find profit somewhere, but that doesn't have to come from the farm. Most farmers also have off-farm jobs.
