> three letter guys would extract your key with a wrench.
Are people still using this to justify no encryption? that comic sure did a lot of damage.
Mr. Nobody should be able to decide how much they want to protect themselves. If it's unstable maybe Mr Nobody is fine with it.
Raising the cost of achieving this to enterprise budgets, just because, seems suspect. Specially when there are so many attempts to undermine secure computing by the powers that be. [1] [2]
> There are many much cheaper ways to force you to give up your keys.
Yes, but that requires the Mr Nobody knowing you have access to them, which in itself is a big deal.
But let's think about it, why would they torture Mr Nobody by wrench? News stations would like to hear that, or do you think they will make Mr Nobody disappear too? Would they take those risks for a Mr Nobody?
Maybe the most realistic scenario is that people sometimes can hold onto their passwords. Scumbag or not. [3]

So we're shaving yaks here but instability undermines nonrepudiability. Mr. Nobody might welcome deniability in the appropriate circumstances...
