I really want to be respectful here but your comment shows a large level of ignorance around the difference between public monopolies, public UTILITIES, public (regulated) goods, and the economics thereof. A lot of public utilities were created specifically to enforce a level of quality and compliance and protect the citizen. In situations where the quality of goods is reduced below a safe level, you should not blame lack of competition, but call it what it is: incompetence at best, corruption at worst.
Good book on the topic that HN readers will appreciate is "The Master Switch": https://www.amazon.ca/Master-Switch-Rise-Information-Empires...
