Because many valuable metals like platinum are dense so most of them have sunk into the molten center of the earth at some point during history leaving relatively small amounts in the crust. This cannot happen in an asteroid as there is nowhere for valuable metals to sink so they remain easily retrievable. That's why so many metals that are rare on earth are plentiful in asteroids, thus making them valuable.
