We're all hand-waving away the fact that there is no un-claimed farmland in the US. It's all owned already. You can't invent your way into possessing farmland. You will have to buy it from someone who no longer has any willingneess to sell it, unless you get lucky and find a dying person with no friends or family. If all we have is farming, no one would part with the land, as it's a valuable, vital resource.
None of this Jack inherits but wants to live in the big city and be an architect. He'll inherit and keep because there is no architecture job to be had.
As someone who grew up on a farm, "you may be a farmer but you could be a productive one" is so intensely depressing. Farming is a shitty job that requires insane amounts of back-breaking labor, never-ending toil, and all this at a time when climate change is going to utterly fuck over farmland and destroy crop yields.
