I can very easily call any of the layers in a secure connection a &quot;seal&quot;.  Besides, it&#x27;s an analogy to demonstrate that there <i>are</i> things that are considered private while in a third party&#x27;s control, not a literal point-for-point template for how to design privacy law for the Internet.  The third-party doctrine <i>does not</i> match any non-lawyer&#x27;s expectations, and it&#x27;s the doctrine that needs to change, not just people&#x27;s expectations.
