It's amusing that a fan of DBZ, who supposedly know as much about the universe as Pymp, doesn't actually seem to understand how various things actually work in that universe.
Fact: The Dragon is only as powerful as the one that created it. In the early series, that would be Kami. In the later series, it's Dende. This is something that is, iirc, directly stated.
Pymp seems to be of the misconception, that being equally powerful, means being able to do the same things. That is not the case.
It only means that the Dragon only has as much raw power, as the one that created it. However, by the very nature of its abilities, it is able to use that raw powers, in ways that the creators(the namekians) cannot.
Kami, and Dende for that matter, is incapable of bringing even a single person back from the dead(make them living again). But the Dragon is easily capable of doing just that. That doesn't mean that the Dragon is more powerful, it just means that the Dragon can use that power in ways that are not available to the Namekians.
I'm not really sure why this seems to be a difficult concept to grasp, I think it's pretty straight-forward.
