Yeah, the manga's theory should be that, think Enel as a cloud of electrons in motion (electricity): they can travel through a conductor but not through an insulator, so they're pushed back. So the gold and any other conductor cannot touch Enel (they will go through him), but here the problem: ANY insulator can touch him! (wood, paper, rock...) Not only rubber... well let's close an eye ; )
