I believe it would be more powerful to petition the IRS to include EVERY form of virtual currency as property and to be taxable like in massive online gaming, in game purchase you can exchange with others, on game consoles, etc, etc.

If World of Warcraft can "mine" objects its players can exchange for money then we should push for a case to make them property owners. US WoW players should be taxed if they make money by selling their property for cash, no matter how small the exchange is. The company should get an audit.

People hoarding expensive URL should pay property taxes too even though they never had the intention of selling. Someone with a very rare twitter @ knows how valuable it could be and so is the IRS.

let's not forget why MT Gox was created for and what platform it was serving.

Of course we need the IRS to tell us what is the official price of a bitcoin at any time in the world so to based our calculation on. Btc-e? Coinbase? MT GoX? Local bitcoin? Should it be based on the exchange the of that transaction even if that change is closed down?
