But bitcoin escrow agencies don't solve the SOPA problem -- once you have a small number of intermediaries paying these websites, they become the place where the law can apply its force. They will be ordered/coerced to stop funding ThePirateBay or whatever site the media industry targets, so these sites either can't have reliable BC payments or they are subject to being cut off by these laws without trial.
Only if they operate in jurisdictions that can apply such force, and only if they make a connection between their online presence and their offline presence. An escrow agency could operate pseudonymously online without having an offline presence, as long as they built a trusted reputation around their online pseudonym and cryptographic identity.
