There was a fundamental shift in the GSE's mission statement in Congress that occurred in the lead up to the financial crisis. It went from responsible lending to lending to anyone desiring a home, irregardless of their ability to pay back the loan. Someone had to pay for this. That burden was and is being placed on the shareholders by Congress and now SCOTUS. Robinhood tactics at the expense of shareholder property rights. Those are the facts.
That being said, there is still a responsibility by the courts to uphold the 5th amendment and give compensation for use of public property.
