A better analogy would perhaps be to consider the land the farm uses as the commons (it was before becoming private property)

We can debate the just access to land (commons) and point to Henry George, John Locke, Thomas Payne and others, but still agree that the value produced by the farm comes from the labour put in to refine the common resource into something more useful.

There can be rent seeking and value produced at the same time.

Edit: One can provably extend the rent seeking parts of the analogy in terms of John Deere and Monsanto
