This is only the case if the business is incompetent and insane, and also not communicating effectively with development. Or maybe things can look that way, if the devs don't understand the business. The business is doing something to make money. The requirements will somehow work to support that something, or will be something that your business contact thinks will support that something. If they don't make sense, that means your mental model of the business is different than your business contact's mental model. And unless your company is unbelievably dysfunctional, that's an opportunity to talk and reconcile those models.
