One aspect that would be interesting is: I would expect that after an insurance payout the stolen coin would be legally the property of the insurance company. The stolen coin would accumulate on the books of the insurance company, which could then pay a premium to a recovery agency to get it back. Of course the anonymity factor would make it all difficult, but on the other hand you can't ever truly abscond with the cash. If they could trace the movement through the ledger to a legitimate business entity that respects the same country's laws, they might be partially recoverable. At a small scale it would be a waste of time, but on a large enough scale it might work.
