Carving up farmland into home plots is easier said than done. Most fields have zero infrastructure, so you need to drill wells, run power lines, streets and/or ROW for driveways. Internet access is pretty easy as you get get a fiber line run. You'll need to work with the local town and county for permits and be sure that they can handle the additional services such as road maintenance, plowing, trash pickup, etc.

It could be done, but it is not just re-drawing some parcel lines and calling a realtor. Even once you get it done, you now need to build somewhat expensive homes to recover your costs, and the FIRE folks will then probably buy that century farmhouse down the street and re-parcel the connected field to keep a few acres for themselves and sell the rest to the neighbor, as they can almost get a house in the country for free if they do so.
