From horizontal to vertical is a huge deal though. The US might have a load of space but plenty of others countries would massively benefit from converting land used for farming into land used for housing where possible. Additionally it means that farming can happen on the edges of towns and cities rather than in the wops, ie fewer huge delivery trucks moving produce around; it can essentially be grown down the road.
