There's efficiency and then there's being a nice place to live. For instance, in my country it's illegal to own farmland unless you're a farmer (not an agricorp) who farms nearly full-time (or at least whose part-time work is related to the farm: value-added products, etc. and not a town job). It's probably less efficient than having Archer Daniels Midland, etc. owning all the farmland, but I think the result, a countryside full of family farms, makes for a much better rural environment.
