While that's true I suppose, whose fault is it for designing a system that is so much more susceptible to "rubber-hose theft"? It seems to me that this threat model would apply equally to anyone who gets rich via Bitcoin, not just Nakamoto, and it's an inherent side effect of refusing to allow banks to act as a trusted third party.
You can't have your cake and eat it too. Should investigative journalism be forbidden from here on to anyone who has enough Bitcoin? Because if it's true that being rich will get you physically robbed then how many Bitcoin startups have founders and officers that are in mortal peril based on their Bitcoin holdings? Surely we can't apply a blanket "no investigate" order across them all.
Rather I believe that, if this is a viable threat, that it's an unintended consequence which is essentially inherent to the new marketplace Nakamoto created, which is something that anyone publically known with Bitcoin riches will have to cope with in the future.
