Enjoy it while it lasts because if the government (USA government) ever gets their grubby hands on bitcoin, they'll try and introduce controls over how much btc you can send at one time.
The US government, just like any government, doesn't control bitcoin. Users do. In the same way they don't control peer-to-peer communication, file sharing-- encryption in general. Not only do they can't prevent you from broadcasting a transaction, but they can't even be sure who's making that very transaction. That's the beauty of transparency. You can verify that the transaction is settled without knowing who's sending to who.
