Let me offer the following perspective, and see if it helps you in your conversation with the GC.
If you are working on a 120V panel and your hand touches something it should not, the current flowing through your hand will force the muscles to contract. That means you will grab the wire or bus bar all the more tightly, and you will not be able to let it go. It is possible, only just possible, that when the rest of your body goes limp, the weight of your falling body will pull your hand away from the panel. It is possible, only just possible, that this will be your only chance of surviving the incident.
Ask me where I first heard this perspective explained. I heard it first from Mike Holt himself. He made it clear that he knows full well that had he not fallen that day, he would have died.
Ever since I heard that story, I have treated the entire notion of working clearance with great respect. Please note that if you have to lean over the dryer to get to the panel, your body will not have the ability to fall.
So then, why is it important not to allow anything in the working space? Because some future electrician will be in a hurry, and not want to waste the time and effort to move the dryer (or the shelving unit, or the boxes, or whatever) out of the way before starting his quick and simple task.
