What you are missing (or I am) is that you neglected to mention that
tamper-proof hardware was involved (or I missed you mentioning it).
Clearly its trivial to trust software that runs on tamper-proof

Ah, right. I remember now. We were talking about trusting a _remote_
system. How do we ascertain that it is, in fact, running on tamper-proof
hardware? Or are you going to say that the software is burnt into the
tamper-proof hardware, and therefore cannot run on anything else, and
hence all we need to do is verify that the software is the software we
think it is (and make sure no-one ever manages to get an image [oops,
major security hole here])?
