I have no wealth to preserve but I do have bills that must be paid. I am also unsure why or how they are harder to take away from you. FDR outlawed private ownership of gold. Yes, many did keep what they had, but they could not use it until that was repealed. It happened once, it can surely happen again. People are taking off with entire ATMs, they can easily take off with your gold even if it is in a safe. But even if you have it gold, when you convert it to gov currency, they have you. They’ll just ask for all sorts of Identifying info and paper work. If I needed approval to cash an International Postal Money Order for $40 (forty) you can bet they can make similar and most likely worse required to convert gold to whatever currency they offer you. These people are decades ahead of us on this.
