What EMT is as a ground is often 10 or more couplings with 2 screws each. That adds up and chances of 1 that got missed is higher. We do not always fasten to building steel. I have done a few parking garages and that can easily be up to 500 feet or more and that is 1,000 screws. Even the very best electricians can miss 1 when they run hundreds of feet a day. Yes if tight connections the steel is a very good ground. What we see in the field is often abuse to the systems from being damaged by other workers and users. Fork lifts can easily open up a section. No we cant make everything perfect.
If you were offered a system with the added ground or without and price was the same would you reject the ground wire ?
Kind of like buying tires for your car. Cheap ones are legal and reasonably safe but some select ones that cost far more. When your going 90 down the highway just remember what you selected.
Perhaps some here simply been working too long in a company that does as little as they must.
