I think he means that everybody should be made to live in apartments or condos, without any sort of garden, patios, etc. Dense urban living for everybody.
Quite frankly, I think such housing areas look far, far better than your typical grassy suburbia.
I do agree that houses with large lawns and zero food crops are just... wasteful. I rent so I am limited to what I could do, otherwise I would just till my lawn and make almost the entire thing into garden beds.
I dislike seeing those houses that have what amount to prairies and on that grass you see just a few horses or whatever. Such a waste of arable land.
