A Failure Tax?

The idea of compulsory insurance for catastrophic risk in the financial system, as outlined in a piece by Jonathan G.S. Koppell seems like an idea worth investigating, pronto! Too many (actually any) too-big-to-fail firms would/do cause far too many resources that should be strengthening our health, education, and infrastructure systems; this would be a way to make the financial services sector absorb some of those costs. I'll be on the lookout for more of these ideas, any of you that have any, let me know!
