I think that stable family units, whether small or big, with children or without, are a benefit to any state.
Ted Olsen explains it much more eloquently then I could.

An excerpt from that article (favoring gay marriage.)
“ It is true that marriage in this nation
traditionally has been regarded as a relationship exclusively between a man and a woman, and many of our nation’s multiple religions define marriage in precisely those terms. But while the Supreme Court **has always previously considered marriage in that context, ** the underlying rights and liberties that marriage embodies are not in any way confined to heterosexuals.” (Emphasis mine.)
Why has the Supreme Court always previously considered marriage in the context of man and woman? Perhaps because that has been the context of marriage since the dawn of civilization.
The fact remains that only men and woman can engage in specifically conjugal relations—that is, marital relations. That’s just a fact of human biology. That fact forms the underlying basis of marriage.
To call a relationship which can never be conjugal “marriage,” is worse than a misnomer. It is to give the impossible the seeming appearance of equality with the real.
We can call a marriage between an elderly man and woman a marriage because it can still be conjugal, even though it may not be fertile. But a same sex relationship can never be conjugal, it can never be marital.
It makes little sense to treat two wildly dissimilar relationships as though they were the same, when they can never be the same. To treat them the same thing is to drain the word ‘marriage’ of meaning. And when the word is drained of meaning, the institution follows the path into meaninglessness.
It is not that same sex marriage is the only thing that will destabilize and sink marriage. Obviously not. That destabilization was begun with contraception, continued with the acceptance of divorce, serial monogamy, extramarital relations, and cohabitation. Marriage had to first be nearly destroyed in order for same sex ‘marriage’ even to be envisioned as possible. So same sex unions won’t be the cause of the death of marriage, just the final nail in the coffin of marriage, because it finally takes the very essence out of the institution and still calls it by the same name.
Contraception unlinked children from marriage; divorce unlinked permanence from marriage; extramarital sex unlinked commitment from marriage; now, same sex unions unlink even the essential sexual complementarity from marriage. Is it dead yet?
