Its highly unlikely because it assumes that people would hand over total control over critical service like water and electricity to one singular decision-making entity. In reality, like they are today, it's almost certain any such public utilities would still be designed to avoid singular points of failure whether intentional sabotage or accidental ones.
You can design against accident .. but against sabotage ? How ? Anything you can do the saboteur can undo. And that's not even bringing the problem of saboteur being smarter than the designer.
