He's saying half of the wealth in the world is just value being stored, and is spread amongst various assets instead of being held in money (because the money the world uses is broken and isn't a store a value). But since Bitcoin is both the best money and best asset (and best store of value), over time, the wealth being held in all these various stores (art, real estate, collectibles, etc.) will move out of its current vehicle and into Bitcoin. Because Bitcoin is the best, and since we're talking about Saylor: there is no second best.
