Right, but then you are operating on a black market basis, because you're laundering money. If the problem gets bad enough the US starts banning dongs, or applying pressure on their government or what not.
Worse yet, laundering money on this basis will almost certainly come with an increased cost to trade through another currency, especially if there is legal risk to the parties doing the laundering.
It's not like laws will stop financial trading or traders, but if you're declaring your taxes as you're legally obligated, presumably there's still a paper trail indicating irregularities if you're funneling your bitcoins through dongs.
