No, it isn’t fundamental at all; in fact it isn’t true! Among the Ashkenazic Acharonim who have argued on Rishonim were the Magen Avraham, the Vilna Gaon and the Baal HaTanya.

I don’t believe this to be true, do you have a source where they are arguing (also if it is, it’s possible that they are holding like a different rishon (as we see where an amora argues with a mefurash mishna and we say he’s going like this braisa etc.)

And Rambam argued on everyone

are you saying he argued with tannaim or amoraim that I for sure don’t agree with you on (my rosh hayeshiva is very big into the rambam and can explain to you every time you think that’s the case)Rishonim he can argue on b/c HE IS A RISHON
