The point was that I have seen you, personally, make the argument in other threads that DMs having absolute power--them being the last word, the decider, etc., etc.--is extremely important, and the fact that some bad DMs might abuse that power is an unacceptable reason to attempt to curtail such behavior. That we should, always, give DMs maximal latitude even though that might, possibly, enable some abusive DMs, because the benefits gained by DMs being able to do whatever they like are massively more common, important, and useful than "protecting" players from bad DMs.
Why is it that safety tools potentially being abused or leading to bad results is a reason to reject such things, but DMs potentially abusing their absolute power is not a reason to reject such things?
