What constitutes an all-powerful government? It seems rife for a no-true-scotsman argument.

Would it be acceptable for a private company to own this information? Perhaps sell it to others?

To me an all powerful government is one that has all the information the user just listed, because governments are by definition the most powerful force in our countries.

Private companies should also be regulated with regards to data sales of private information, yes.
