Yes. Which has essentially happened already is Greece. What doesn't happen is people being put in debtors prisons and told that they have to pay back every cent despite all avenues of reparation being exhausted. Do you honestly believe Greece has the capacity to pay back all of what it owes? If yes, then how? If no, then why not write the debt off, or at least reduce it to cents in the dollar so that the lenders can reasonable recoup some of their losses on the risk that they took lending to Greece in the first place?
I'll note you totally changed your argument. Funny how these things happen when confronted with facts.
As for your question, because Greece apparently needs external motivation to pass necessary reforms. Syriza thought that by threatening to exit the Euro they'll be allowed to ignore the necessary reforms. However it is evident this same tactics need to be used against Greece.
It's comical, really. A normal country would want to reform so the same thing doesn't happen to it again. Greece, especially under Sryiza, is doing all it can so it will suffer the same fate over and over again.
Debt relief should be used as a reward for Greece for passing necessary reforms, not as a reward for insulting creditors and calling them "terrorists" for not throwing enough undeserved money at them. Greece is acting like a small spoiled child, and if it is to be kept in the European family it needs to be taught manners. Sad, but true.
