I want to write a comic book about a superhero in his 20s who comes from a very wealthy family but my friend says its stupid. Should I give up?

I'm writing a story about a biracial superhero. He's in his 20s, and his dad is a Black billionaire. His mom is Japanese, and she comes from a wealthy family. I don't want to give too much away, but there is something about his family's history that resurfaces, and it connects to his powers. He is basically trying to find out what it is. My friend says the story is stupid and no one would want to read it.
