The Deadweight Loss of Christmas

Economist Joel walfogle wrote a paper titled the deadweight loss of christmas. He argued that it made no sense for me to give you gifts that you don't like, and for you to give me gifts that i don't like. We would both be better off keeping our money and spending it on the things we do. Like bill has many disputes with how economists see the world of money. The problem is that if you imagine a world where all debts are settled, then what is that world? Society is not a society of settled debts. There's no moment where it ends.
