Carl,

You are a good writer, which is most important, and you choose interesting topics, also important. 

What you don't do is get the "angle," which is your unique way of looking at a topic (here, art). 

So I popped off to inspire you. For example, sell all national treasures and distribute the coins to the citizens. Years ago, England sold the old London Bridge, which I think is now in Arizona. Better than selling it as scrap metal. Be controversial as what's the worst someone can say: "You're wrong"?

You might be, but they have to write their own paper to "prove" it and then you can rebuff them.

Keep writing.
