"Now let's be fair, you took that "there is no justification" out of context."
Did I? He says, "it won't work if you don't"...as to mean that the government cannot borrow unless some sort of interest is imposed.
I offer this...tell me why this would not work, I'm genuinely interested (a bit long so, sorry):

"As a sovereign government, Congress' power is unique. It can create money debt-free and interest-free. Congress needs to stop thinking of itself as the same as other organizations that must take money in before they can spend it. Money does not grow on trees. It must be created. The only choice is whether to have it created as loans at interest from private banks or to have it created by Congress debt-free and interest-free.
How can Congress create money without causing inflation? Congress must regulate its value. The power to create money includes this regulatory power."

"Guernsey is an island state located among the British Channel Islands about 75 miles south of Great Britain. In 1816 its sea walls were crumbling, its roads were muddy and only 4 1/2 feet wide. Guernsey's debt was 19,000 pounds. The island's annual income was 3,000 pounds of which 2,400 had to be used to pay interest on its debt. Not surprisingly, people were leaving Guernsey and there was little employment.
Then the government created and loaned new, interest-free state notes worth 6,000 pounds. Some 4,000 pounds were used to start the repairs of the sea walls. In 1820, another 4,500 pounds was issued, again interest-free. In 1821, another 10,000; 1824, 5,000; 1826, 20,000. By 1837, 50,000 pounds had been issued interest free for the primary use of projects like sea walls, roads, the marketplace, churches, and colleges. This sum more than doubled the island's money supply during this thirteen year period, but there was no inflation. In the year 1914, as the British restricted the expansion of their money supply due to World War I, the people of Guernsey commenced to issue another 142,000 pounds over the next four years and never looked back. By 1958, over 542,000 pounds had been issued, all without inflation.
In 1990 there was $13 million in interest-free state issued notes. A visitor to the island that year later wrote:
"I returned from Guernsey last weekend. It is a fascinating little island. There are about 60,000 permanent residents on the island. The average family owns 3.3 cars, their unemployment rate is zero and their standard of living is very high. There is no public debt. There is a surplus of public funds which earn interest. The Guernsey Treasury increased the Ml of the island by 40 percent in the last three-year period, and this increase did not do anything to inflation. The price for a gallon of gasoline in England translates to about $5US whereas, the price in Guernsey is about $2US. Contrary to the teachings of current economics in all higher institutions, inflation is not related to the volume of money but rather to the size of the commercial debt."
Sovereignty proposes that Congress create money and lend it interest-free on a per capita formula to tax-supported bodies for capital projects and to convert existing debt to non-interest-bearing debt. Since first proposed in January 1989, the Sovereignty loan plan has been endorsed by over 1,814 city, town, and county governments and school boards, as well as by the U.S. conference of Mayors, the Michigan state legislature and the Community Bankers Association of Illinois, which represents 515 banks."

"When that slows the economy, we will be told to spend more to stimulate the economy. We have heard it all before. Neither method works. We need debt-free interest-free money to fund the work that needs to be done. It's not sacrifice we need; it's productive employment. Let Congress use its unique power to coin money and regulate its value to fund that employment."
