There isn't. I wouldn't mind there being no governmental involvement in the marriage issue. However, when the government grants benefits based on marriage, it is important that we do not discriminate against certain folks without a compelling state interest.

I think you may be looking at it backward; we've seen the unintended consequences from the well intentioned tinkering with marriage and family law over the past 50 years. Family is basic to society. If you want to tinker with it, show there will be no unintended consequences. "Why not?" doesn't cut it.
