The problem is that most farmers in the modern era are completely reliant on a combo of government subsidies and massive amounts of bank debt in order to stay afloat. It's a pretty huge problem and part of why the industry is massively consolidating. Also there are things like being required to license patented seeds, tractor/combine companies prohibiting personal repair of vehicles/equipment.. I don't think medium/small farming as we think of it will exist in a couple decades.
