I think the technology is still quite immature for this to be honest. There is a lot more work to be done. What we are talking about is distributed databases and applications that aren't run by anyone specifically, but right now this is still difficult to do in a lot of cases. It currently only works in cases where there is certainty in all aspects of the business transaction.

Let's take insurance as an example. There is still loads of uncertainty in the risk level assessed, the various features that will be covered in the policy, the corresponding cost of the policy, the claims assessments on the level of damage after an event. You can't do this as a simple distributed ledger. This requires human interaction and some serious process management. Most businesses have end-to-end processes like these. It's only fully discrete business models that can currently be enabled by distributed ledger in a clean and straightforward way.
