I would argue that's not really a trade, at least not in the sense described in the article, since it lacks awareness and consent from one party. The bees never agree to the trade of providing us honey in exchange for the hive and protection, and most likely see no connection between the two events. They simply stay in a hive they have found while it's convenient for them, and when their honey is unexpectedly taken from them they will survive on sugar water that they conveniently find outside the hive.
