Between 100% of people growing their own food and 1% growing for 99% of the others is a wonderful range of opportunity we should return to. One person or corporation owning and managing hundreds of hectares with the help of giant machines doesn't scale either, it's currently destroying the planet. The guys on the big tractors are the grandchildren of the people grandma was forced to sell her garden too. I'm sure the human species is ingenuous enough to come up with something that guarantees people's dignity and feeds everyone.
