To your first point not really. If guess you could stack 2-3x as many dishes in a cabinet that takes up the same space as a dishwasher because you could arrange them to take up much less space. It doesn't take many plates and bowls to fill a dishwasher but that same amount wouldn't take up half the cabinet. But you could probably also get by with less.
