Assuming that you can create value of 11 or more with that 100, someone can exchange 11 of their future / current / past effort (with money), (s)he pays you, you pay your debt, and you now have 1 or more to be at the other side of the transaction.
Unless you state that all value in the world is fixed, a zero sum game, that argument of the "Money as debt" documentary doesn't really hold water.
