Isn't the whole point of Homecoming and then doubled-down on in Far From Home that Peter isn't meant to be the next Stark, but that he should forge his own path? The point of said villains is to show that the way Stark did things had a lot of faults and that he wasn't always necessarily the best guy, and that while he was a positive influence in Peter's life, he's definitely wasn't someone to model yourself off of.
