Of course they buy real things for it. And of course they do buy a lot and take up a lot of resources.
But I think it's orders of magnitudes below what their wealth number suggests. For instance, I don't believe that Elon Musk uses hundreds of square kilometers of living space (US average is 66m², scaling by wealth would give Elon hundreds of square kilometers). Same holds for food, heating, medicine, etc.
