If one has the bucks to just tell somebody else to "do it" I wonder about the actual enjoyment. If all you want to do is look at fine model work, I believe it is just as easy to call up a world-class modeler (Chris, or John, or my friend Greg, for instance) and visit. Especially if you can afford a Learjet and a Chauffeur to get there.
I could be wrong - I have friends who enjoy watching someone else have all the fun - airshows come to mind, or Polo games . . . Lots of folks just love to watch while others play Golf.
I do not have as many trains as CO did, but I built most of them from sheets of brass, and I sure get a kick out of glancing at them while wandering through the display area. Somebody else can sell them when I head west.
