Yet this is exactly what happened in developed countries in the 20th century, now many of these are again privatized with the predictable loss of efficiency and increased bureaucracy (supporting frameworks, arbitrage, watchdogs, etc...).

In my country the privatization of public transit and energy companies has been a total disaster. I remember when I could get things done without being pingponged between 12 different parties, things that used to take a day now take weeks.
