It's more about people with a lot of money hoping to sell it for a greater return, while maybe also having shit taste in art. In five years it'll be at an auction and sell to some other person with too much money in hopes of making a profit on it later on.

There are tons of interesting tricks you can pull once you have your hands on a small object "worth" hundreds of thousands or millions of dollars whose very illiquid + inefficiently priced sales also affects an entire market of similar objects.
