Resources farmed is not the same as food produced. If you consumed all food produced but had stocks of farmed resources that could be used to make more food (wheat, sesame, beef, onions, say) then with excess capacity you could readily produce more food. Our supply chains are such that we can go from field to table in a day, that allows us to go field to freezer (or canning factory, or whatever) too.

This perhaps relies on non-capitalist management of food production however.

tl;dr I don't agree with your conclusion.
