Well because in the eyes of the thick-browed grugs who were writing the setting? Alignment had to be in there and dragons of different scale colours had to be different alignments, it's not D&D without alignments and they're not D&D dragons if they're not colour coded!
In the canon of the setting there is no great conflict, the dragons all know what their singular god wants, he wants them all to play nice and tickle each others pickles, its just some dragons are biologically cocksucker-coded by Io because he's got that wildcard bitches energy apparently.
If the writers had engaged their brain for a moment then you'd either not have alignments in this setting or it'd be used in a useful way, something like:
>Alignment is the philosophical position the Dragon holds towards reality as a whole, do you see yourself as a steward left by Io? The rightful heir of all he created for you who has divine permission to do as you see fit? Are you not sure? ect, ect
With humans being an entirely separate alignment outside of the axis: their alignment being 'Fuck Dragons, all my homies hate dragons, you don't rule shit, get down here so I can stab you, you big, scaly fuck.'
But they didn't because they don't understand the function of the alignment system and so they can't play with it, change it to suit them, do interesting things with it, it's just something to be left alone and when it doesn't fit the setting they want? Worked around.

Dark Sun & Birthright are another two settings where alignment is a poor fit, just as proof that it's not a one off thing.

The emergent gameplay that comes from ACKS systems is the single best groundwork for a sandbox campaign out there.
You can scrabble, claw, whine and shart all you like, but the game speaks for itself.
