Actually, I think the context of the discussion was if one was to decide to give back their home to the bank and decided not to move out and live for free rather than going and renting. Within that context, living for free has a beneficial influence on the economy. Rather than leaving the residence before eviction. That is what Brian responded to.
Obviously there are adverse affects to not paying back debt in regards to banking. Though, banks seemed to have missed that simple point.
