I agree with your point. I think that what some people are trying to say is that a lot of stories that work for most superheroes don’t work as well for Superman. A typical superhero story is one where a bad guy sets up some bad situation (robbing a bank, holding someone hostage, threatening to blow up the moon, opening a portal to Hell) and the superhero tries to respond, and after some dramatic fighting and struggle the superhero comes up on top.
For Superman, for the most part he can take care of the threat with little effort, unless you use a cliche like kryptonite (and you can’t just have everyone carrying that around all the time). So that usual story doesn’t work as well.
Now. I think you just have to write a different story. And frankly, it’s probably going to be a better story. The “bad guy is a threat and good guy punches them until they are knocked out” story is kind of inherently bad anyway.
So in a way, by naturally guiding people away from that tired comic book trope, you’re steering the writer toward something better. I’d argue that it makes it easier to write a good Superman story.
