In a truly free market this particular financial crisis would never have happened
In a free financial market there would have been no official endorsement of the illusion of safety like the one generated by the bank regulators when they created the minimum capital requirements for banks based on risk and that led many to believe that, as far as the risks goes, the banks had been equalized. And of course neither would the market have suffered the distortions that originated in the regulatory arbitrage of these capital requirements.
In a free financial market no one would have given so much credibility to some few credit rating agencies paid by the issuers of debt and therefore there would have been no opportunity to peddle in the market such an extraordinary amount of such extraordinary lousy awarded mortgages to the subprime sector.
