I agree with the downvote and the fact that borrowers have skin in the game, but not that lenders have none. Debt should not be dischargeable, else it's not debt at all.
Of course debt can be written off. Out there in the real world contracts are renegotiated all the time. More of that would be advantageous in the face of information asymmetry, the party with better insight would be less tempted to exploit their position.
If you're referring to the fact that it can't be discharged as part of bankruptcy, then I tend to agree with you. It should be.
