On a more serious note though, those use cases are real and specially useful on totalitarian countries.
Well even in some countries where the citizens have control over decisions for their nation, it is entirely subjective to the citizens themselves if they find decentralization useful
We all have different reasons as to why we all like decentralization maybe others use it for business or maybe others are just really private and would not want their information being spread either way i think it is up to the person on how they will put decentralization to use
