Average person spends minimum of $300 per month on food. [1]. Low housing estimate is [2]

Simple robust agriculture can provide:

Chicken-fish-rabbit combo with cows - but takes close to 1000 acres of 1000 acre EPCOT with 10k acre buffer. [3]
Venison - for 10 square miles, we have less than 1 lb per person per year. Fuggeddaboudit. [4]
Integrated into EPCOT - we should be able to do 1 acre per per person for full economy- 10000 acres for 10000 people - tapping 20% of the current available land of 5 acres per person in this world. But that is more like business as usual - with integrated design perhaps providing 1/10 acre per person. That is 40 kW solar (10kW average) - which should be sufficient for all use including industrial. If food were part of natural ecosystems. So based on solar income - the theoretical minimum must be around 10kW average energy production - or 1/10 acre.
Solar income tapped via vertical cities - using solar steel and concrete - [5]
