Does it really have anything to do with originality?
I wear clothes, but people don't see me in my clothes and laugh at how sheeplish I am for doing what everyone else is.
I tend to wear certain types of clothes, and even though such clothing has been worn before, nobody thinks about them in terms of originality. The same goes for my haircut, my shoes, my choice of beard/moustache (or lack thereof) and, for girls, their make-up and other decorations.
If the fact that it's been done before many times means that we should ban it, the first place to start will be marriages, especially ones in churches, and the wearing of gold rings. Huge numbers of people have a gold ring on the ring finger, the tramps! How boring!
