Also: money. Answering the question of how to name the streets is expensive (doubly so with the nasty political infighting), putting up street labels costs money too, and all of this creates plenty of opportunity for some parties to line their pockets. With that in mind, it's not surprising if the locals find the proposal not cost-effective.
That glosses over the question of how to name the streets, a question quite conductive to nasty political fighting. Maybe that already happened.
