I welcome the notion of taxation of profits made in game currency. It's only fair. There is, of course, no obvious and simple way to maintain game activities and game gains as a going concern while requiring players to liquidate some of their game profits into real world currencies. Individual accounts lack the resources to do this efficiently.

So if game profits are to be taxed, there is only one possible outcome: real world taxes will have to be payable in game gold. From a gamer's perspective, the advantages of such an approach seems obvious.
