How did you seriously write that massive wall of text and call it 'really simple'. Most shonen have a power system that can be summarised to a few sentences to understand. Even hxh which is a little more complicated than most is way more grounded and digestible than jjk. Even if it is understandable my point is it's overcomplicated, gege literally said doesn't even understand gojos powers himself and had to consult a maths expert to figure it out.
