"The debts are unaffordable. If they won't cancel the debts I would suggest obstruction; you do it yourselves"

This quote by Jeffrey Sachs suggests that the debts are too big to be settled. He is suggesting that if the financial institutions won't cancel the debts, then the debtors should take matters into their own hands and obstruct the creditors. This could suggest that the debtors need to refuse to pay the financial obligations, or take other steps to prevent the creditors from gathering the debts. Sachs is suggesting that the debtors ought to decide and not allow themselves to be benefited from by the lenders. This might be viewed as a type of civil disobedience, as the debtors are refusing to abide by the demands of the lenders. Ultimately, Sachs is suggesting that the debtors need to take action to secure themselves from the financial institutions, even if it means breaking the law.
