>Alignment is bad for storytelling
wrong.
RPG stands for role playing game. Its about playing a role in the world, alighment helps to cement that role.
In a fantasy world, morality is absolute.
In my opinion people that disregard the moraltiy axis are a detriment to the game.
Did you know that there have been thousands of stories written where characters have a moral code and a role, without the entire framework of the universe bending to put a box around every single character? That's called "character". The box isn't needed to have characters which have a moral code (or lack thereof).
Worse yet are frameworks which put the box around every single race/species, so that an infant of that species, too young to have much of a mind of its own, is considered to be inside a box just for being a member of that species, so that Drow baby is Evil without having actually done anything.
The point of alignment in D&D is not to lock players in and say "You can't do this thing because that act is 3 points too chaotic for you", it's a framework to help players build their characters identity and keep it consistent. If they do not, that shifts their alignment. Alignment change is a thing in the game which can happen, so your "moral relativism" is already built in.
