Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
But it only deals with getting positive balances moving - it doesn't handle the problems that can occur on the debit side (which aren't mentioned in the example of course).

If participants are obliged to return 20 coupons at departure, falling below those 20 coupons is effectually a negative balance.

If the coupons are depreciating at some rate, you can go into the negative balance just by doing nothing. You can go deeper into "debt", but there is a floor. Wouldn't that be useful and somehow fair "debt" system?
