I think you are headed in the right direction wrt a capability system,
however, they are predicated on tamper proof hardware. Since you
stipulate human being copying and torturing (sounds like tampering
to me), I think this is not ultimate privacy.
Hmm, perhaps you should set up a key escrow system (!) so that you need
to call your most trusted friends to assemble your session key. The
session key works only once, assuming a tamper proof, capability system.
When you call them, they can quiz you on your mental and physical health
to determine whether they should give you the keys...thus limiting the
ability of a torturer.

Oh, sure.
"Hi, Paul? This is Marc. I need your piece of my private key. How
am I? Just fine. But if you don't give me the password, the guy
holding the phone has some very unpleasant looking surgical equipment
and there isn't an anaesthesiologist in sight, so I won't be fine for
long. Just read it out loud, someone will key it in."
Need I say more?
