The "guy with the gun" narrative comes up a lot, so this seems to counter that? I love the concept. It seems like something that would work well in a movie but fail miserably in real life.
Author here and I wasn't really thinking of this as a useful use case either. Most of my consideration was say corporate espionage or journalists working in authoritarian countries where killing the person would create a highly visible incident. Mostly was just a thought-experiment turned into a real implementation. With any tool like this the risks/benefits should always be considered.
This is really good, I've had a gun pointed at my head more than enough times with all my bitcoins wiped, finally a solution to my every day problem.
I got a chuckle out of this. Only the paranoid HODL.
