I would be more interested to see your response to the key point of their comment - that the US exemplified this on a large scale in recent history.

That would be more compelling than to simply claim to have a lot of knowledge of history

I don’t think the World War II economy is repeatable today. It was a time of great patriotism with the majority of the nation supporting the war. People were willing to sacrifice for the cause and accept rationing of goods and making substitutions. They also knew that these sacrifices were temporary and helped their loved ones win the war and hopefully return to them sooner.

Today in America it is hard to get more than half the population to agree on anything. There is no unifying catalyst to bring about the consensus, cooperation, and personal sacrifice that would be necessary to implement a centrally planned economy in the United States today.
