I don't agree with this analogy. Unlike cryptography, TPMs have been designed
from the ground up to serve an evil purpose. They *could* have designed
them with good intent, for example either of these could apply:
- Buyer gets a printed copy of the TPM's private key when they buy a board.
- An override button that's physically accessible from the chip can be
used to disable "hostile mode" and make the TPM sign everything. From
that point physical access can be managed with traditional methods (e.g.
locks).
But they didn't.

The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and
how) you may access your data; but nobody's threatening your freedom: we
still allow you to remove your data and not access it at all."
