Consider just the aspect of randomness alone. How can the universe implement it? It seems like a really awkward problem. [But the Everett interpretation gives it to us for free](https://www.preposterousuniverse.com/blog/2014/07/28/quantum...). It really seems like a killer argument to me.
That just deals with the random nature of wave function collapse, not the mechanical nature. Wave function collapse can be used to move around particles, or rotate them etc. A single measurement is just a normal random chance, but you can do a series of measurements over different basis you start to affect the system in non trivial ways, you can use that to control position or rotation or other states of particles, MWI doesn't explain that part at all.
