That is to say the children of exceptional people are usually average, not exceptional.  I definitely think there should be the ability for groups to separate themselves.  For instance, I wish there was a vegan city. I wish there was a diy city. I wish these cities had entrance requirements. I wish there was a black wakanda city. I wish there was an interstellar oriented city.  People should be allowed to segregate based on any feature they want to.
