> Agriculture is hard work and not at all profitable unless the operation is at scale.

You seem a bit confused. While that is more or less true for the farmer, it is that way because the landlord usually takes most of the profit. As is to be expected. They hold all the cards. You can't farm without land. But given that in this scenario you are the landlord, not the one doing the work...

The key to farm profitability is to own your own land free and clear. But, of course, unless you have a high paying job doing something else instead of farming that's really hard to pull off, so most farmers end up renting (either to a landlord directly, or renting money from a lender). That's when you need scale to make up for the vast majority of the profit going to someone else.
