I don’t think the statement about playing gold during a National Emergency is accurate… unless I am misunderstanding the definition of National Emergency.
We have, I think, 31 National Emergencies currently in force. A number for many many years. See below.
From Wikipedia…
As of February 2019, 59 national emergencies had been declared, with 31 of them being renewed annually. These include the eight that were declared prior to the passage of the 1976 Act.[1][4][19] The longest continuing national emergency dates back to November 1979 by the Carter administration blocking Iranian government property under the International Emergency Economic Powers Act.[20]
Since passage of the National Emergencies Act in 1976, every U.S. President has declared multiple national emergencies: Carter (2); Reagan: (6); H.W. Bush (4); Clinton (17); W. Bush (12); Obama: (13); Trump (4).
