The sky may weigh just enough to prevent someone from escaping it. So Atlas would constantly have to focus on holding the sky up or he would be crushed by it. Same could be said for Artemis or any person holding it, meaning the weight of the sky could shift depending on who is holding it at any given time. However a god or Titan's energy may constantly replenish itself, so they could hold the sky forever. Demigods are still mortal and only have so much energy, so they will eventually be killed by the task, as it isn't a punishment meant for mortals anyway.
