I think I have an answer.
Peeps like my ex wife simply cannot abide leaves cluttering up a lawn, or fallen fruit to step in or animals that may come for a snack. Trees shadow lawns and kill grass, leaves get in the gutters, trees need care, an lawn can be handed over to "someone else" to deal with.
Those same people would rather waste precious water on useless ornamental plants like grass and hibiscus than have it bear fruit.
