I assume the idea is that because Rarity had to produce dresses in an assembly line rather than individually, she stopped putting a personal touch into each one, making them all exactly the same. Also, because so many of the same dress were sold, it was no longer unique. The "Rules of Rarity" is just the idea of artisanship.
