I don't really buy into this argument. Regulating the sale digital goods works. Companies that wish to remain legal will refrain from the sale of digital goods in an illegal manner; mandatory company audits will be a vector governments use to enforce that. The article and others in the thread have given arguments that digital goods are not victimless. Most societies acknowledge that gambling is harmful; digital gambling with fake money or with time spent in-game is presumably harmful as well.
