Asteroid belt got all the atoms to make the cake from, the only issue is their arrangement, and they're presently arranged in a specific configuration that is as unlikely - as low amplitude - as if they were arranged into a bunch of cakes. It's just that the highly unlikely configurations that look like asteroids are far more numerous than ones that look like cakes (which is a property of the looks-like-cake function).

Basically, it's a common fallacy to believe that coin toss sequence such as HHHHHHH is less probable than HTTHHTH. It isn't, and if you were to throw a quantum coin in a quantum many-worlds universe, the world where it was all heads will have same amplitude as every other sequence's world.

(Also, any "stray flows of amplitude" require non-linear Schrödinger's equation, of a very very specific kind so that you don't end up with essentially one world)
