Yes we need anonymity but in case of legal actions all bank account must be transparent in the face of the law. In our country there was a bank secrecy law that even the banks cannot expose the transactions made by their clients to the government authorities for legal purposes. Big syndicates find this as a haven for their profits since it is hidden by the banks in secrecy thus bank secrecy law must be conditional and will be deemed invalid for the pursuit of legality and truth.
