Earlier quoted context omitted.
There is a difference between inflation, which affects the entire monetary system, and money expiration which affects individual units of currency. In the first case, there is no incentive to use the money any faster, and as long as inflation isn't too high, there could be incentives to hoard/save it. In the second case, each unit has an expiration, and like the game of hot potato, you want it out of your hands quick…
The question then becomes - when is the money created? Is it created when it is issued by a (central) bank or is created when an exchange (for value) takes place? (the later has an interesting side effect as it would incentive to make transactions legal)
"Ich möchte das nochmal klarstellen, ich redete (schon was her) nicht von 'Zinsfrei' in Umlauf gebrachten Geld, aber sehrwohl und im Interesse aller Beteiligten, von Schuldfrei (i think 'debt-free money' would be the word in english, and against debt driven creation of money) in Umlauf gebrachtem Geld."
And explicit nothing from the Muzzies "economical"-stuff!
