It’s fine to say that we don’t entirely hold like the Rambam on this issue, certainly because mainstream Shittos are far more mystical and less rationalist than the Rambam was. But trying to answer it up and say why it works within the Rambam is, frankly, an insult to the Rambam
But unfortunately, people today apparently wouldn’t be able to come to grips with the idea that there may have been some pretty extreme machlokasim on some awfully fundamental issues. And there is also the “mitzvas asei chiyuvis to answer every shver Rambam” mentality.
