Here you circumvent the major issue by not addressing the concern.
If the design itself does not prevent it, then the extortion attack
cannot be prevented; contractual arrangements do not help, clearly.
Am I correct that you propose that the system should be designed in
such a way that there is zero protection against remote extortion?
