I think there is a difference between the Rambam and someone today in that the Rambam didn’t have the benefit of the gedolei Rishonim and Achronim.
You must be joking…Rambam IS gedolei rishonim. Absolutely ridiculous to say that Ramabam needed any rishon or acharon to clarify his shita. And that we have better understanding of Torah. Too funny.
