Occupy Wall Street is not a bank. They are purchasing the loan from the bank. The bank may be able to take a loss on the sale of the loan to OWS, but that is irrelevant to what OWS does with the loan once it is their property.
If this doesn't happen then the government loses revenue and it also opens up the possibility of people using loan forgiveness to dodge taxes.
Well, yes. And the IRS will certainly pursue cases where it is clear that loan forgiveness is used to dodge taxes. But that is not what is happening here. OWS is purchasing loans to help people get out from crushing insolvency. The alternative is the debtor's declaring bankruptcy, in which case no one--not the government, nor the private creditors--gets anything. Note also that OWS is a non-profit entity, so issues of tax revenue loss are generally irrelevant.
