Who is "we"? In the case of my own system I payed for (so speaking for myself) 
I would like to have such a mechanism to have the system prove to me before 
login that it is not tampered with. The TCG approach does not provide this. Oh, 
and predetermined means that the machine admin can declare to which known state 
the system is going to boot.

Here the TCG approach would also be helpful as the remote attestation against a 
central server (or a number of them) can help. 

And for the RIAA guys, they have no business on the machine I did pay for (!), 
as long as I do not infringe their copyright. Assumed innocent until proven 
guilty! On the other hand, there has been an infamous record company that 
miserably failed  to ensure their components on consumers' computers are _not_ 
a security risk.
