That's true in any individual case. But if we make it our social norm that bankruptcy is nothing to be ashamed of and to be taken lightly, won't it change the equilibrium for future generations of lenders and borrowers such that an inefficiently low amount of lending goes on? If everyone has the expectation that the lenders and borrowers will try their best to live up to the contract they made in good faith, wouldn't it be a better equlibrium? And we can work towards such a world bit by bit in how we respond to crises like the Puerto Rico one.
