Why I Was Won Over by Glass-Steagall

I have to admit that I was not a big fan of the forced separation between investment banking and commercial banking along the lines of the Glass-Steagall Act in the US. I do not like restrictions to contractual freedom, unless I see a compelling argument that the free market gets it wrong. Nor did I buy the argument that the removal of Glass-Steagall contributed to the 2008 financial crisis.
