I definitely agree with the direction this article takes but need to comment that with available land with a third set aside for nature and another forty percent desert, degraded or high altitude mountains, of the remaining land a part set aside for connection infrastructure and organisational buildings like schools, production centers, the available land for 8 billion people is limited less than half a hectare per person. In thinly peopled countries like Brazil, Russia or Canada this model would work but in many other places, India, China, Indonesia, Egypt, etc, this model would simply not be applicable.
