Why are you fixated to the idea of one person owning every single entity? Who owns the ministry of energy in Nepal? Not the minister, not Prachanda. It's the Government of Nepal. Comprende? Government is an an entity, just like a person. Government owns NRB with its CEO as the Governor.

>who is govt of nepal? 601 members of parliment is the government of Nepal?
In a way yes, they control the policy of our Government. Government also entails public officials.This doesn't mean these people are share-holders and that they share profit from its operation.

>if federal reserve is not owned by private banks, then who; god owns it?
Again, why does one person have to own it? The 12 banks have share on Fed reserve, but the share are unlike any public or private entity- in that the share holders don't take the profit (they do get divident IIRC) from FED's operation. Not one person owns it.

Ownership of Governmental entity is unlike private or public company. I think this is the point you are struggling with. Hope this clarifies.
