If they could get the Dread Pirate Roberts, they can get anyone; however, it's most likely he was just spooked and decided to disappear.
I've long thought a journalist with sufficient time and resources would be well rewarded by looking through obituaries of IT personnel. It seems like no one ever considers the possibility that Satoshi was some middle-aged guy with high blood pressure and an unhealthy diet who had an unexpected heart attack and died without leaving anyone sufficient instructions to access his accounts & wallets.
Ross Ulbricht was arrested in San Francisco
I'd be very curious to see how they would get him if he had settled in, say, Beijing and naturalized there as a Chinese citizen. Regarding Satoshi unexpectedly passing away, I often make such remarks myself, but this is a dead end obviously in any sense of the phrase. It is more interesting to speculate that he is still alive and simply hiding in some forest hut keeping away from the public eye
Or just rotting in one of the
numerous secret CIA prisons somewhere in Poland or Thailand
