Ok, I see where you are going, but personally I still think the destruction of coins is not the way to go. Unless all parties are already using this system to determine a market value for trust in the destroyed coins, then there is absolutely no incentive to use this system for any party.
I could definitely see an alternate system dedicated to this purpose, where an organization would purchase "credits" at some price in BTC that would work like bonds. If you use an alt chain, this would allow for a market to buy and sell credit to give those credits an intrinsic value that would work for the 'close up shop' honesty factor. The special rules for fraud could be built into the chain though: if the organization is behaving dishonestly (rules TBD
...), all of their credits, or a percentage of their credits depending on the amount of fraud, would be liquidated and returned to the defrauded individual. So more like traditional insurance, but decentralized.
