I'm only half joking. I honestly don't see what the difference is. And, I certainly see a potentially significant financial benefit
Just so we're clear, you're only "half-joking" about direct-line incest. And incest, as I explain immediately following, almost exclusively, means child molestation.
And, for the record, I'm not sure I support a law against incest. The problem is that incest almost exclusively (I'd say exclusively, but I'll leave myself a tiny bit of room) originates with the sexual abuse of the child.
*I teleport us to the world of things that are completely false.* Assuming the two, let's say father and daughter, are both adults and there was no psychological, sexual, or physical abuse (no way) and both want to enter into a sexual relationship (see why I took us to this magical land?), then any offspring they produced would have major medical and developmental issues. This would be the biological issues with your argument. The psychological issues would arise from the abuse that almost assuredly occurred.
As far as familial relations outside of direct-line relationships (brother-sister, father-daughter, mother-son), I don't much care. Relationships between cousins and further-separated familial lineage may be socially odd, but I'm not sure they're a problem.
Truthfully, in my mind, your argument is along the lines of the "if gays can get married, why can't I marry a goat?" argument. Unless you seriously want to support a father/daughter sexual relationship, the purpose of your argument is to create a non-issue that detracts from what could otherwise be a logical, educated, even religiously informed discussion.
And the next common argument would be polygamous marriages. Due to tax reasons, a person can only marry one other person. And polygamy takes advantage of the welfare system (multiple children under one, or more likely, no income, since the "husband"/father is legally married to someone else) which causes further and financially large issues. In practice, though, I couldn't care less if you want to claim to be married to 30 people. Because it doesn't effect me. (In this case, the claiming to be married, and indeed, actually religiously married to X people, but economically, there are issues as explained.)
