The problem: If you've an antique for sale, then, sad to relate, the world isn't your oyster. It's not that easy. Even if somebody gives you the National Gallery, your options are still very, very limited. Okay, you can sell the Old Masters, set up a trust, buy your favorite brewery. But that's strictly it. You're limited by honesty on one hand and law - that hobble of sanity - on the other.
