If the depowering works similar to like if say Superman and Zod fought under no Sun, but one of them had been like that for a long period of time before the other was teleported, then he'd have a point. Considering who's making the argument, I wouldn't put much faith in it being the right argument. But even a broken clock is right twice a day, so maybe.

Exactly. Lets not even forget the fact that he went through back to back fights before losing and dived bomb head first from the moon to Earth. Before losing, he had just finished fighting Thor, dived back to Earth, fought Hulk again and then fought Thor.
