I think what we have here is a case of status quo bias -- new things get subjected to more intense ethical scrutiny because they're new. Selective breeding of humans has been around for as long as there have been humans; it's what people do when they choose a mate. Evolutionarily, this is simply a matter of trying to choose the most advantageous genes to mix with yours, to maximize the expected propagation of your own genes. In practice, it is a eugenics program on a vast scale, and nobody seems to have a problem with it, despite the fact that it "provides an echo-chamber for certain discriminatory beliefs" and can lead to inbreeding if you're reckless. All that sperm banks do is amplify this selection.
