I could see if bitcoin was the backbone of our financial system (which I believe is starting right now with the NASDAQ trials) the U.S. Government could possibly become the world's largest miner in order to help assure the security of the bitcoin network. They wouldn't sit by idle while China does the majority of the mining. Then I think other governments would join in to insure their own security as well.
This could also provide revenue for the governments possibly alleviating the tax burden placed on citizens.
Is this a possible outcome??
why spend millions on mining equipment when they can just spend $500 an hour to hire a lawyer and judge to get warrants to steal bitcoins, cost is probably $2k max
