Umm... that's not at all what I said.
It may not have been what you meant, but it is what you said:

The only reason
this should be a law is because of
the need for genetic redundancy. If human DNA had fewer flaws, then there is no reason why
incest should be illegal.
"should be illegal", "should be a law" = state intervening on breeding,
"need for genetic redundancy" = the reason being genetic quality.
QED.

All I'm saying is that incestuous relationships have a disproportionate chance of producing unhealthy offspring, and that it is immoral to subject one's children to that if avoidable.
So does a maternal age >35 years (incidence of trisomy 21 strongly increased; takes off wildly beyond 40). According to your reasoning, breeding beyond the age of 35 should also be illegal.
So does a relationship where both parents have a recessive trait that predisposes the child for hereditary diseases. Should all people then not be screened for that and those found wanting not be barred from breeding? After all, it is immoral to subject one's children to that if avoidable.

I suppose that we're fast approaching scenerios like that described in Gattaca where the state actually could approve/disapprove genetic couplings based off of a list of known genetic disorders, but that'd still have the negative reprocussion of whittling away genetic diversity.
I sure do not hope so, because that'd mean the work of all biologists since Gregor Mendel would have been in vain. And that would be the least worrisome consequence.
