[Dragon Ball] If the Dragon can do anything Kami can do, why does Kami need to gather the balls during the Freiza saga to wish everyone back to life?

I mean, if the dragon does anything Kami can, why doesn't he just bring them back to life without the dragon balls?

His power is limited by his creator, but his powers are not the same as his creators. He can't do things like kill someone Kami isn't strong enough to kill because Kami simply doesn't have enough power to do that and so neither does Shenron. It takes X amount of power to kill someone, and so if Kami doesn't have X amount of power then neither does Shenron and so the wish is beyond him.   


Reviving people isn't a matter of having enough power (for the most part) though. It's just a different kind of power. Kami doesn't have that ability, but he was able to make Shenron who has a wider range of abilities.
