I have no idea where people got this "intrinsic value" stuff from. Something has value because we prescribe it value. That is all.
I told you already where intrinsic value comes from. Try surviving without the star we call our Sun. It has intrinsic value to us. It's essential to our survival.
Sorry, I hadn't read your post

I can't think of an argument against that; however, intrinsic value when applied to gold makes little sense, which is where I often see it coupled. It has some handy qualities but nothing we couldn't live without.
