This falsely assumes that economic actors necessarily have sound judgment about value. Imagine someone who has had a bad day at work going and spending $10 for the privilege of being rude to a fast food clerk. If given the option would they directly trade the humiliations they themselves endured to earn that money to be able to inflict the same? Probably not, but their workday is already over, they don't see a way to translate the cash they have onhand into an overall better life, and this is what they feel like doing in the moment.
