But the point wasn't about holding business to account. It was about impact. As it happened Oracle was in the end one of the last states in America to get its exchange up. To great detriment of the people. And that was not critical infrastructure.

Forget accountability. Its about risk/reward analysis. The risk if a company does this with something like water is that millions die. Such a risk requires a truly massive reward to even be considered. So where is this reward? What benefit can privatization offer that's so significant it is worth risking millions of lives for?

You don't have competition. You don't have market forces. More than a few water privatization projects have been disasters as companies were derelict in their duties and caused great environmental and social harm. So the risk is real. Where is the massive guarantees benefit to offset that risk?
