I'm reading Libertaria in Cyberspace by Tim May. I've never seen this one before and it happens to be very relevant in 2025.

"Obtaining an entire island is problematic. Getting the consent of the residents is one issue (familiar to those on the this list who weathered the Hurrican Andrew diversion debate). Being allowed to operate by the leading world powers is another…the U.S. has enforced trade embargoes and blockades against many nations in the past several decades, including Cuba, North Korea, Libya, Iran, Iraq, andothers. Further, the U.S. has invaded some countries—Panama is a good example—whose government it disliked. How long would a supertanker “data haven” or libertarian regime last in such an environment? (Stephenson’s fascinating Snow Crash didn’t address tthe issue of why the “Raft” wasn’t simply sunk by the remaining military forces.)"

The same is true of transporting gold in a world where oil tankers can easily have oil confiscated. I know there's a gold block chain, but it still requires "trust me bro" technology.
