What you are missing...

Physics is practiced by hand, pen and paper or chalk and blackboard. There is no IDE or auto-completion.

The short hands, abbreviations, and obscure syntax raise the difficulty to enter into the field but simplify its practice a lot. In fact, it would be nightmarishly verbose if you had to use more explicit terms to the point of making it almost not feasible.

Furthermore, the complexity of learning a few shorthands is incomparable with understanding the underlying concepts. Just because you name things in a more verbose manner and used a more explicit type system you wouldn't be any closer to understanding what any of this means. The effort of learning a short-hand notation to express a concept that takes years of advanced math to grasp is negligible in comparison with the speed up it offers day to day.

The notation is not what is stopping you from understanding it.
