Where does x come from in this setup? Is x is arbitrary given a, so that it only guarantees that a can only manipulate you in ways that it could have done via giving you information (if I could persuade via some argument to do what I want, then it’s okay for me to just pull a gun on you if it puts you into the same state)? Or would you have some additional assumption about the information in x being a “reasonable equivalent” of a?
