Quick review in case you missed where BitCoins went: dollars will always have intrinsic value because the US Government demands payment in dollars. Tax payments are only accepted as an electronic transfer - from the institutions SOPA controls.
So SOPA is bad news because:
1. You can't escape the bank-controlled economy, so you will always need US dollars or whichever currency is accepted in your country.
2. You can't prevent large organizations (those with hefty legal departments) from issuing at-will takedowns on competitors.
3. Takedowns won't be just for The Pirate Bay. Good luck winning your court case.
I simply believe this is the only chance to retain freedom of speech. SOPA must be defeated.
