Banks stocked with the frozen sperm of geniuses already exist. They haven't created a master race because only a tiny number of women have wanted to impregnate themselves this way. Perhaps a grieving couple whose child is dying. This might seem psychologically twisted. But a cloned child born to such dubious parents stands no greater or lesser chance of being loved, or rejected, or warped than a child normally conceived.
Infertile couples are also likely to seek out cloning.
Currently, if this couple wants a genetically related child, they have four not altogether pleasant options. They can reproduce naturally and risk passing on the disease to the child. They can go to a sperm bank and take a chance on unknown genes. Or they can get a male relative of the father to donate sperm, if such a relative exists. This is one case where even people unnerved by cloning might see it as not the worst option.
