> The limitation on gold ownership in the United States was repealed after President Gerald Ford signed a bill legalizing private ownership of gold coins, bars, and certificates by an Act of Congress, codified in Pub. L.Tooltip Public Law (United States) 93–373,[1] which went into effect December 31, 1974.
The government has armies so not respecting whatever laws they pass is hard and potentially deadly. In some cases it is worth it, but typically people are better off respecting whatever laws that are put in place.
"Hi, Costco. We would like to subpoena you for the customer records for every person that bought gold. Note that 'would like to' means 'are going to, and you will comply'. Love, the US Government."
"Hello I'm agent smith from federal agency group, costco said you bought some gold, where is it?"
"lost it"
"Mind if we search your house?"
"i've known you were going to ever since I bought the gold; knock yourself out. Just please don't disturb my antique collection of locked filing cabinets. They're all empty but the keys are in that big pile over there"
