On the fundamentals of charge

What is charge? why is there a positive charge, why negative? why is it a fundamental universal constant? why do we similarly have the universal constant \(\hbar\) of angular momentum. Why is the electron is so small and the proton so large, similarly when it comes to mass? There are truly a lot of questions that we would like to have answered when it comes to how the world works and frankly current physics is although one can calculate things, not explaining anything in a proper way in my view. An answer to these questions is tried to be formalized and analyzed in this paper On charge.
