It's like any other asset with a market value. Collectible baseball cards have no inherent value to me (I'm not a baseball fan), they're just (mildly aesthetically attractive) pieces of paper. In that sense, they are similar to Bitcoin. That some people will pay several million dollars for them does not change that fact. If a drug dealer settled all his transaction in baseball cards, the FBI would of course confiscate them.
