The line is quippy, but it's silly when you look at the batman stories. Anything can be funny if you get reductionist with it
When the writers have her saving plants, they do it in a way that you root for her. Same with Mr. Freeze, those episodes and the movie is really touching, solely because of his motivation.
You don't root for batman to beat them up or flex his wealth on them, you want Batman to help them. You want them both to get happy endings.
The stories usually end with batman stopping the carnage, while also arresting whatever CEO was cutting down trees or doing experiments on Nora. In other stories, he funds social programs and advocates for reforms as Bruce Wayne.
Maybe there are other stories where he acts like a frat boy. I skip content that has shitty writing
