I think you can also see aspects of this + the way it interacts with the human tendency toward altruism in the success of One Red Paperclip and later imitators, who repeatedly made progressively larger positive-value trades until the combined effect is that they'd traded something of effectively no worth (a single paperclip) for something of substantial worth (a house, car, etc.): people will intentionally and knowingly make negative-value trades for someone with charisma or to be part of a good story!
