In the Chapter You Read That It Costs the U

In the chapter you read that it costs the U.S. Treasury's Bureau of Engraving and Printing around 5 ½ cents to print a $1 bill, 10 ½ cents to print a $20 bill, and a bit over 14 cents to print a $100 bill. It seems the Treasury could generate a nice profit for the government by simply printing currency and using this currency to purchase the goods and services the government needs. In fact, this seems to be a way to eliminate the problem of budget deficits for the U.S. government. Comment on this idea.
