To say that every possible thing, within all degrees of freedom, happens at every moment in time, is to say that the probabilities of the wave function are *isotropic*. But we know they're not. When you describe many-worlds in such a naive way, and you consider what the mathematics of that must be, you see it has no resemblance to Born's rule, or Schrödinger's equation.

So you're trying to impose an intuitive understanding about what the multiverse must be like onto this picture. The problem is, it's not intuitive at all.

In fact, even the insistence of thinking about these branches of the wave function as separate universes is a mental shortcut. They're not like different dimensions, with 100% copies of our entire universe. They're different branches of the wave function. That's it. Now, does that mean that there are different branches where your life turned out very differently? Yes. There's an exorbitant large number of such worlds. But your macroscopic considerations, such as whether to put milk in your coffee or drink it black, are *emergent* descriptions of the world of decohered quantum systems. These are not branching points. That's a silly Hollywood trope.

The branching happens at the quantum level, as described by the Schrodinger equation. And there is no wave function collapse. What we observe as the collapse of a wave function is where we find ourselves on a new branch of the wave function that is decohered from other branches. That's it. That's all it says. Human choices, and human-scale decisions are not really relevant to this world. To understand many-worlds, you have to understand the math, and stop trying to use mental images of what branching worlds look like.
