Why couldn't the government offer those loans directly to main street until the credit freeze subsided? Just take one of the worst banks, nationalize it when it goes bankrupt, sell everything except the lending branch and use it to lend to main street with printed QE money. Divide it into bits and sell it when economy looks good again.
