Indeed, you are correct. I had not taken that into account. Thinking
about it from that perspective, there's no way to depend on proof that
the someone received something (e.g. a payment) without also allowing
the receiver to block payment by refusing to provide that proof. That
invalidates this class of solutions.
Thanks,
