Land could be real estate, which, if not just sitting idle, it's still the epitome of rent-seeking.
Plus, land rented to farmers is productive because of the farmers, not because of the land -- and would still be a sinkhole of money from the middle class (the farmers) to the rich person doing the renting, not entering circulation like the money a farmer would make (to buy animal food, seeds, whatever, and to live their family).
