I'm so tired of this stupid mantra that crypto-addicts keep repeating.
1. You can't put real world events into a blockchain in a decentralized manner. In no fckn way. How are you gonna put a result of a sports event into a blockchain? By mining what? It's ridiculous. It always should be an oracle, authority, company, government, etc, i.e. a centralized trusted entity.
2. Loans. Yeah, loans to anonymous entities that can just transfer money to another wallet without any possibility of reversal.
3. Digital ownership. It's nothing without a possibility of a forceful defense of this ownership. You bought a house on a blockchain, but previous owners don't want to leave. What are you gonna do? Call Satoshi?
