The whole POINT of bitcoin is that the p2p model avoids subjugation. Despite the government's best efforts from Napster to Megaupload, p2p file sharing is still going strong.
Pirate Bay offers links to torrents, that put bits and pieces of data together from potentially millions of computers all around the world, Napster offered a free p2p service and although Megaupload was a (vast) profit making company, as far as I am aware it had no shares listed on any stock exchange.
Whilst two of the above internet phenomenena have been taken down and/or controlled, plenty other alternatives have sprung up in their place (if they never existed already). Whilst the creators of Pirate Bay may well be doing time, the Pirate Bay lives on and the only way to kill it would be to kill the internet (as it presently exists) altogether. Bitcoin of course, mostly resembles the Pirate Bay model, so it will be nigh on impossible to take it down by conventional means.
As mindtomatter has already extensively covered in his 'Central Bank' thread, it would however be a piece of piss to sabotage Bitcoin by means of a technical pump n dump attack. Whichever Wall St bank or group of banks need not even lose money in doing so, as once they pump enough capital into the market sufficient enough to cause a hysterical herd stampede into the coin, they can in a measured manner, start extracting their coin at great profit, thanks to the flock of fools queuing up outside MtGox, with big bundles of fiat in their fists. THIS SH!T HAPPENS ALL THE TIME! And it is happening now.
I was a relatively early user of Bitcoins (1st Silk Road purchase made in late 2010), and enthused to my brother about the whole concept and the massive potential they held as a game changer on a global scale. At the time, he was completely dismissive and couldn't give two craps. Recently, he has been at me constantly trying to get more info on Bitcoins, what they are, how to use them etc etc. I have to admit here that when Bitcoins were at $45, I put him off. I stated that the underlying market of real transactions that underpins the whole viability of Bitcoin, is becoming an exponentially tiny portion of the entire Bitcoin market, and that this is a bubble of the riskiest kind. I still believe this, although the bubble has trebled in size then, and my brother has lost a projected £20K worth of profit due to listening to me. Anyways, he has now wired £10K into his newly established Mt Gox account, the money will take 4 days to arrive. He still does not understand:
What a Bitcoin is
What a Bitcoin wallet is.
What the Bitcoin Dat file is.
What a Bitcoin client is.
etc etc.
This is the calibre of newcomers rushing into the Bitcoin market, and thus helping prop up the already hyperinflated prices. No enthusiasm for the concept of the coin or understanding of it, and certainly no means of ever using them as the currency that they are supposed to be. He is motivated only by the opportunity to make vast profits. And of course, first sign of a pull back, eating into any profits he has made, and he will be out of there, as he has no other use or purpose for the coins, other than to make a profit on the fiat currency he is putting in. I imagine that most new money coming into Bitcoin right now is coming from people like him.
