I might have to concede that the whole thing is untenable unless you actually enjoy geeking out about the game theory and mechanism design and whatnot.
This feels more like a stunt to get people interested in their start-up company. The wife is so far in debt that it looks more like gambling with fake money at a Casino Night since the game theoretic model seems it breaks down when there is cost-free debt.
But I don't actually understand that objection. Seems analogous to taking Walt Whitman's side in this exchange: http://www.scottaaronson.com/writings/whitman.html
