And the reason I find that implausible is because the godlike powers part makes any sort of personal growth hard when you don't have any respect for human institutions in the first place.
Why, because with "god-like powers" one can't be broken under the yoke of one's limitations and the power of those institutions to reign people in? That's a pretty dismal take on how and why people mature in their outlooks.
I'd think that one thing Clark's got to realize as he becomes even more powerful (he can't fly yet) is that while he cannot change the world to suit his concept of a just society without actually ruling
us, there are things he can do to protect people and the planet in ways that no one else can - and that he's hampered in doing that by escalating conflict between himself and human authority.
