I think it's because the ID numbers are one of the few things you cannot replicate. You can't change it. With colors, you can scatter to change the dragon, these days you can even change the pose of your dragon. I myself don't collect interesting IDs, but i definitely get why some people like them. It's something that's totally unique to each dragon.
