I can see if the e-mails I got claiming to be from my mother are really signed by her computer or not.

Which is the problem with the whole idea of trusted computing. What if your mom got herself a new computer? What if you upgrade your system?

The problem with TCPA and the likes is that it's tied to the system and not to the user. If you get a new system all your protected content is just so many gigs of useless bits.

Catastrophic hardware failures do happen, and would be even more catastrophic if the data is hardwired for a particular system.
