But you can multpliy location by building up (there is some energy and time inefficiency in having to go up and down but in theory you can also build multiple layers of transportation), so how that works?
I see how it works but all you're doing is making more efficient use of the given parcel of land. The value of the land already prices in its development potential. A parcel that could legally, physically, and feasibly accommodate a high rise will be worth more.
