>the many-worlds interpretation is basically the result of saying it doesn't

Few problems with this, the state that a particle can be in after the collapse of the wave function follows a probability distribution, so if all states are equally real then why does it seem like some states are more likely than others? Why would probabilities be such a powerful mathematical tool, and how would it work in a MWI.

If all points of the universe branch out into several universes after each particle interaction, where does all this energy come from? If all branches are equally real why even have the wave function in the first place?

Because some states are more probable than others. That is what the wave-function tells us. It does not give equal probability to every possible outcome.
