Many games do things different than GW2 do, and many games and GW2 make money and expand their playerbase in their own way.
I am sure Anet have done their calculations and thought it through, before they used time to develop the wardrobe. You clearly do not like the idea of it, while it seems that some other people are content with it.
Feel free to raise a thousand threads on this issue, but I does not seem that a lot of people agree with you, and I do not think Anet will roll the wardrobe back. Maybe your time is better spent simply ignoring the wardrobe and focus on the rest of the game.
