The use cases are: regulatory arbitrage, crime and grift. That's it and that's all folks. Nothing more. Everything else is better solved by classical means.
The golden rule of blockchain is: if you think blockchain solves any given problem better than a classical solution you either don't know enough about the problem, or you don't know enough about the blockchain.

[edit] As always, it's important to remind crypto folks that outside of the cult, ad hominem attacks are not suitable replacements for fact.
