The allegations in Choke Point were that banks were approving transactions they shouldn't have, without doing enough investigation to check for fraud, not that they were failing to move money from one account to another, the "problem" that blockchain is supposed to "solve".

In what way is blockchain supposed to prevent fraudulent transactions? It is impossible in blockchain to even check for fraud, because every transaction is automatically irrevocably approved by-design, no matter how fraudulent.

edit: unless, what you meant to imply, is that the banks weren't supposed to approve those illegal transactions and so the government stepped in to punish them, and that bitcoin is good because it will never deny an illegal transaction and is therefore useful for committing crimes? well then thanks for admitting it, I guess.
