That includes confiscation of gold and other “alternative” forms of wealth.
Central banks own over 80 percent of the world gold. 1930’s gold was used in coins and convertible to paper certificates. In order for gov to control it they had to take it out of circulation. There are ways to avoid confiscation. Buy gold jewelry in lieu of bullion. Gov cannot outlaw jewelry stores if they decide to confiscate all forms of gold. Since most of the world gold is in the hands of bankers, there is no need to seize it. Seizing it will make foreigners dump dollars even faster because most of the USD is stored in overseas foreign banks. IMHO a major currency collapse will lead to a currency reset and a new asset will be used to back the currencies of the world. If the dollar is not the reserve currency it will be devalued after the bank holiday is over. Look at what happen in Argentina and Mexico recently. People who owned hard assets were able to exchange it for more of the new reset currencies thus preserving the buying power of their wealth. People who stuck to paper money ended up exchanging all their savings based on paper currency for a smaller amount of the new reset currency. In Mexico people lost 20 percent in the first reset (and it happened several times) and it happened several times. In Argentina people lost up to 90 percent of their buying power in the first reset. Today the Fed Reserve has up to 10 folds of US dollars in circulation or digital form. If US lose world reserve currency status and must reset to how much USD exist vs its gold reserve in Ft Knox and Central Banks, you may find the reset currency may be 1/7 or 1/12 (depending how one calculates it) of today’s worth. Savers and pensioners will be in big trouble, and anyone in debt will be in big trouble.
