the guy is still in your house and knows you still have control of your funds. he knows you would rather give him the funds .. eventually .. rather then send them to an address with no known privkey (losing control yourself knowing you will never get them back ever).
so he will hammer you until he gets the multisig, privkey, safety deposit key, privkey where funds were diverted to.
i guess the cartoon did no explain that enough
This is exactly true. If you are in physical danger there is no reason to try to protect you money/bitcoin.
Money can be replaced, your life cannot.
You don't know, and neither do I. I find your fear of death to be irrational, especially in light of the known suffering of existence.
If if I were to accept your argument that is would be a possibility, if you really started over then your bitcoin would be lost regardless.
