You’re thinking from a collectivist point of view which typically leads to statism. Idk if you realize that. When you put the collective good above the individual good, you inevitably centralize power. I’m not for or against race mixing or “racial purity.” I’m against anything that violates individualism. You may want white states but not all of those white pooele want that. So the only way for you to achieve that goal is through state violence.
