If you can describe one which doesn't involve something related to a checkpoint, or human intervention, I'd be happy to add that to the OP.

If 10+ block reorgs are made public and require human intervention then it's enough to solve the issue. It's exactly what happened during Bitcoin Fork 2013. The knowledge that humans can intervene is enough to stop anyone buying the keys. All that is possible in this case is an expensive prank. But you decided to exclude "human intervention", well, never mind then, perhaps you have strong arguments to exclude Game theory from the security equation...

Human intervention largely indicates a critical failure, the resolution of which must happen under centralised control, so we arrive back at the original conclusion again.

Yes, bitcoin had just such a critical failure as well, and it nearly destroyed the currency.

Instead of silly hypotheticals, what about using other blockchains as the TTP?
