Line work, where someone is using a grounding set for protection. The set has to be sized adequately for the fault current available and placed correctly to protect the lineman. To give that worker the impression that "any" type of ground applied in "any" manner will save him "because it takes the path of least resistance" would get him killed.

I assume linemen know their job and understand what it takes to make themselves safe while working. I also assume electricians unserstand current will flow in any path it can.
So how is this saying making the world unsafe??
