I would have government defend the life and property of all citizens equally; protect all willing exchange; suppress and penalize all fraud, all misrepresentation, all violence, all predatory practices; invoke a common justice under law; and keep the records incidental to these functions. Even this is a bigger assignment than governments, generally, have proven capable of. Let governments do these things and do them well. Leave all else to men in free and creative effort.
I agree with a lot of the points in Taleb's book, but I don't agree with many of his conclusions. It seems to me that he rightly points out that risk managers miss a lot of the risks, but the conclusion is that he draws, is that we should abandon risk management, whereas my conclusion is we should improve it.
