Most of those situations you listed can be solved, and solved better, in a normal centralized way with often the same experience to the end user. And they don’t really care if you’re using block chain or AI or magic as long as it’s solving their problem so why would you choose Blockchain for the heck of it?

I see blockchain being useful in two areas, finance and transport/delivery logistics. Environments where no one trusts each other outside of financial contracts and you need to share information publicly to address faults and concerns without other parties being able to change anything.
