Maybe. But I think the basic flaw of that sort of agriculture being extremely labor intensive and therefore expensive remains. It's hard (and unlikely) for us to scale up a very expensive labor intensive way of doing things in a world where most people in even well off countries neither want, nor can afford, to spend a lot more on food than they currently do. And while labor is cheap in poor countries, another important goal is helping poor countries become better off.

Also we reap a ton of environmental benefits by having most people live in or around cities. Move a ton of people back to rural areas so that they can work on labor intensive farms and we'll pay a big environmental cost for doing that too.
