I always thought that Jack was at full power because he wasn't a Guardian, he was just a regular spirit. So therefore, his power isn't boosted or weakened if children believe in him. I mean, he could do all of those things without ANYONE knowing he even existed. But that could also fit in with your theory, maybe you get double the powers with the catch that if kids stop believing in you, you basically cease to exist.

Dang, you're right, I hadn't thought about Elsa's powers compared to Jack's. She made a friggin' castle out of ice.
