So, I can see that argument following for something like Bitcoin. Though I think that part of that is because cryptocurrency doesn't actually have any intrinsic value. So an attack on, say, the Bitcoin network would also have the effect of devaluing the very thing you're trying to compromise.

But it does seem to be something you need to contend with when looking for new uses. Most new ideas people are thinking up have to do with something that exists outside the blockchain itself. And that, not Bitcoin, is what Azure Blockchain Service was really about. The merits of cryptocurrency as an application of blockchain are largely irrelevant to this discussion.

My sense is that the general pattern for most other uses is that the number of potential legitimate participants in the blockchain system is likely be inversely proportional to the overall importance of the thing the blockchain is trying to manage. Everyone can get in on something like CryptoKitties, but there are probably very few natural participants in a blockchain network for managing nuclear fuel resources.
