Well, as long as not all nations ban trading bitcoins for official state currency it doesn't completely screw things over. I simply trade my bitcoins for Vietnamese dongs or whatever and then exchange my dongs for dollars.
No, the collapse is more likely to happen on its own. At some point the massive increase in value must draw to a close. What happens then? Big bitcoin holders no longer have an incentive to hold onto their millions of dollars' worth of bitcoins "Hmm, time to sell some of these bitcoins". Millions of bitcoins hit the market and find no buyers at the quoted price. All of a sudden the price is a lot lower, folks panic, drives prices even lower.
In an asset where the only incentive to hold the asset is the massive increase in value, panic selling happens as soon as it looks like the massive increase has gone flat. The steeper the increase, the steeper the decrease. That makes bitcoin unlike gold.
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.
