They forget little problems like this.
Also, as regards to clothes, fashions change all the time. Even in a utopia there's bound to be changes in clothing due to preference or to combat boredom of wearing the same thing. But then if the "kings and princes" ruling from heaven are dictating to us what to wear (no tight pants, skirts to a certain length etc) we're actually gonna be living in North Korea. Can men grow their hair in paradise? Or will there be a list of 5 acceptable haircuts like in North Korea?
No cool haircut. No cool clothes. No hot girls in spandex. No emo girls. No goths. No Rammstein. No more Quentin Tarentino films. No eating meat.
Shoot me now! Oh wait, you cant, im immortal. Noooooooooooooooo!!!
