If you're worried the evil gov'mt is gonna steal your gold, then why won't they just steal your BTC too?
There's a reason why Swiss safety deposit boxes of gold exist. You gotta pull that crap out of the country. Hell, if the US Government just declared ownership of the BTC Network through subpeonas, they can effectively 51% attack it and double-spend all the BTC they want anyway.
There are more holes in these economies than their respective governments has fingers to plug them in.
Flight to bitcoin is the only natural and logical progression.
