No confusion here. A monopoly, whether held by the state or a corporation is never going to offer a product that will compare to those produced under a system of free competition.
We are now looking at a whole string of failures brought on by government monopolies in education, retirement, health care, postal service, and home loans. Without competition or a need to meet standards of quality and economic efficiency the product produced ends up being one that no rational person would purchase unless forced to do so.
