I mean yeah I can agree with the gist of it... not really sure they tier them out quite like we have. (Why I think many found it kind of silly to have say, hawkeye and black widow in the original avengers). superheros generally are just set to be a match for.. their respective villains.
Obviously the super hero universe thing people have to close their eyes on is the concept of the over the top OP heros nearby are generally equipped well enough that they could usually overcome all the "street level" villains over a lunch break.
To my knowledge that's kind of it with Luke Cage though is more... he doesn't have any major mobility or solving advantages. So effectively the way villains need to work around him is... don't get close.
You know what, he actually wouldn't be horrificly wrong if he were actually pushing for something there. Lets say hypothetically our jobs, aren't real work, and it's no big deal that they are replaced.... the actual intents of progression of technology... was originally that when the ratio of work needed to be done and people shifts... we'd work less for more pay etc... but no we just capitalism it and say "labor is in high supply, so we need to cut it's price until people can find use for it".
