Well, I think I said so (about resistance) in a manner of speaking in my post. But that was tongue in cheek (this is an expression to mean a joke of sorts).
I'm not sure if English is your first language, so excuse me for using English expressions!
Anyhow, the point about resistance. Think about the dancers on the dance floor again, in their "duality" dancing upon the dance floor. In order to dance, they need a floor upon which stand. Without a floor, the dancing could get quite difficult!
Think of resistance as the dance floor, with voltage and current doing the "dance". The floor is necessary for the dance to occur, but the dancers aren't dancing with the floor, they are dancing with each other. The floor is just a "condition" that effects the dance or permits it.
So in this way, the duality is occuring between voltage and current.
I enjoy using metaphors when I describe things. I hope it makes it easier to understand.
