Magnetic monopoles are less popular. Most grand unified theories, in their simplest forms, predict we should have already seen proton decay. We haven't. So that's good motivation for inflation. Roughly, inflation can inflate away the monopoles. You just have monopoles, but there's less than one per observable volume of the universe. That's why we've never seen them. The so called cosmogical monopole problem, is less now than it used to be. It seems to me you are equally dismissive when you say the world just evolves according to the schortenger equation. What does this actually mean? How do a 60 % probability evolve into the real world
