But how would any of that help in this case? They didn’t break his wallet, they didn’t force him to transfer money personaly. They kidnapped him and his wife and then cut off his finger and sent the finger to his associates asking for money. The transfer would be initiated by the associates who are free. What would a panic code help there? The only thing which might change things is the ability to reverse transactions. That would make the kidnappers keep them longer. At the cost of making every transaction on the blockchain less trustworthy. Not really a clear win.
