Sure but now you need a $5 wrench to essentially force a guy to tell you where he buried the gold, rather than just walking to the bank and taking it. I don't see that as some kind of win for the guy with a wrench, especially when you realize the bank manager is way less likely to be a violent nutter sov-cit.

The solution is to store your money on a wallet where you do not have the private key. This way if you cannot access your funds nobody will be able to coerce you.
