I’m not contesting what you said, just pointing out that there are added risks for the Libertarian “geniuses” who think they can escape the reach of the bad ol’ state by using cryptocurrencies. They may see taxation of their money by the U.S. as theft, but keeping their money in other jurisdictions opens it up to the more direct form of theft, depending on the whims of their governments.
For various reasons, I’m familiar with offshore banking, although I don’t use it myself. There was a time when a lack of international regulation allowed safe options in stable liberal democracies like Switzerland or (in a roundabout way) the Channel Islands, but now that’s not an option.
