True, but in the case of "money nationalization" the best thing is not to have gold, but your money parked offshore already. They can frisk you at the airport, x-ray your luggage and find your gold bars too. Probably they'd incarcerate you "as a terrorist financing suspedt" if you tried to do that. By the way, historically Jews collected diamonds for the purpose of rapid wealth transfer under duress, as they had to get up and leave right away a few dozen times during history. You can sew a hidden pocket into clothes and put your compressed carbon there.
