It's a very good question. As to a condition required for this to operate safely, I think it depends on having a clear set of morals and values in society that we agree on. The West has lost that after the boom post WWII. Maybe it will find its way back, and "moral authority" will be something people mostly agree on again. I think the way we get there is by debate, so we need to be able to openly talk about and criticise a whole range of ideas, nothing should be off the table during the debating phase. As to the operation of it with supervision, hopefully, for those of us in democracies, it operates in the same way that our democracies operate, where the guards of the people are guarded by the people. At least, that's the idea, right?
