Are you actually that dense, or are you being obtuse? Of course, the initial loan amount is owed. So when I say a debt is attached, it means it's added on top of the loan amount, that's called interest.
What I mean by scrapping interest, is that no extra debt is created when money is loaned after being printed. If 500 is loaned, 500 is owed. The way it currently is, the loan amount is owed plus interest, creating a debt that can never be paid because there isn't enough money in existence to pay it.
The Germans had a saying - "One Mark for one Mark's worth of work or goods produced". This is how they solved the inevitable hyperinflation of the international system.
They went from a situation where you couldn't buy a loaf of bread with a barrel of Marks, to being the richest nation in Europe within 3 years. That's why WW2 happened, it was a clash of economic ideologies.
