This is not intended as "how to grow all your food you ever need at home".
It merely provides the vegetables.
You still have to get your grains (and therefore the majority of your calories) from somewhere else.

I think the idea is that is an alternative to lawns, patios, driveways etc on already residential land, not a replacement for crops on already agricultural land. In fact, if all farmland was replaced with plots like this I don't think there would be enough people on the planet to live on them!
