So, basically, you are forcing your standards on someone else. I’m not objecting to that—simply that people are forced to a moral standard. Every law forces a standard on those who object to the law.
Are you also suggesting a world order that sets the consensus?
So, whether by a book that is supported by consensus or without a book that is supported by consensus, you are stipulating that morality is never a real standard since it always fluctuate. (We have seen that through the ages) One could say that in “some cases” - it would be different but not wrong.
If there is a God (or gods) He wold set it (or they). If enough believe there are no gods, then they set the standard.
And for the cannibals in the Amazons, they certainly would enforce their standard on us as we greet them
