Sure, and that is why I mentioned it.

However, TPM-based solutions have applications beyond this one trying

full-disk encryption all over the place and I figured that people
might be interested in how they work in this context.

And that would be why I implied that this wasn't practical in my very
first email.  This was an entirely hypothetical exercise, and the
first two lines of my email summed up the state of common software
that purports to do this sort of stuff.
