I’ve made a little bit of money on the “Diablo III” real money auction house by selling virtual goods for US dollars.
I push some numbers on my numberpad, someone buys the item I have for sale for the numbers, those numbers are transplanted to Paypal and then to my bank account. Recently I used those numbers to buy a french press on Amazon.com; I took the numbers that were sent to me, sent them to Amazon because I wanted a physical object, and received a french press through the mail.
It was magic, I typed in numbers and an object arrived a few days later with no physical exchange or difficult work involved.
This sparked an understanding; dollars are pieces of paper, gold and silver are shiny rocks from the ground, and the medium of exchange called money is an idea that people assert power to.
It shapes the way most people live, but it’s just an idea and only has strength if you believe in it.
