If people have rights, unequal outcomes will result and trying to impose equality will violate their rights. It is as simple as that.

Murray Rothbard in Egalitarianism As a Revolt Against Nature states the point in this way: "An egalitarian society can only hope to achieve its goals by totalitarian methods of coercion; and, even here, we all believe and hope the human spirit of individual man will rise up and thwart any such attempts to achieve an ant-heap world. In short, the portrayal of an egalitarian society is horror fiction because, when the implications of such a world are fully spelled out, we recognize that such a world and such attempts are profoundly antihuman; being antihuman in the deepest sense, the egalitarian goal is, therefore, evil and any attempts in the direction of such a goal must be considered evil as well."
