I suppose I was thinking along the lines of: if a nation state, or group of nations, or banks - the kind of people who have a vested interest in devaluing bit coins - decided to attack the Market, what would happen? They would be free to use tehniques they can't use is real money markets, such as artificially inflating values ( via rtt) or misleading investors. Plus, they have large amounts of real money. Bit coins are a nice idea, but you can't buy a house with them. These are the kind of groups who have Pockets deep enough to invest enough to cOntrol bit coin, and also lose that investment in favour of longer term gains. And no matter how they do it, no one would have any meaningful legal recourse.
