AFAICS none of your points addresses the problem posed by your parent commentor: someone accidentally sent a lot of money to the wrong account/wallet and wants it back, even if the receiver is uncooperative.
I'm not sure we understood the parent comment the same way but you're right, you can't get your money back if sent to someone uncooperative. However, you can call the authorities and prove that you sent funds to that person and let them recover it if possible. I only addressed the question of attribution.
