We have have indeed been over this, so you shouldn't make the same mistake. This was the earlier corrective(s):
Meh. Seeing how the California State Supreme Court doesn't agree with your "corrective", I'm not willing to put much stock in it myself.
As noted by your own reply, each is considered a benefit to the state, thus the wherefore is the same. Marriages may produce children and form a stable basis for raising them. Quite simple.
No, not so simple. The question isn't whether
marriages in general provide societal benefit, it's whether
the regulation of marriages (and its effects in terms of quality or quantity) provides societal benefit.
That is right. Our concern is state sanction wherein there is a duty imposed on the state and the state draws a benefit.
Which is what, exactly?
And again, we're not talking about the overall benefit of marriage in general, we're talking about the incremental effect of state sanctioning of marriage vs. not.
Yes feral children or any variant of the same.
How big an issue do you think feral children might be? :sarcastic
If people wed and produce and aren't seeking state endorsement or benefit they are a separate topic.
No, it's not, because they directly apply to the issue at hand: people who would marry and have kids regardless of state sanction are a sunk cost (or "sunk benefit", if that's a real term). They're common to all alternatives, so they cannot be considered to be part of the benefit of state sanction of marriage.
Arguing whether the state should be concerned with marriage is a separate discussion.
No, it's not. The purpose of marriage, and therefore the needs or wants that state sanction of it are intended to address, are at the core of the issue.
Insofar as the state is concerned with marriage, the rationale is because there is a benefit the state derives. That benefit is new citizens and new tax payers. Relations that cannot produce new children therefore are outside the bounds of a state vested interest
Why exactly would increasing the population be of benefit to the state? New citizens represent new taxpayers, but they also represent new costs to the state. In an ideal situation, the net effect of an additional taxpayer on the state would be neutral: over his or her life, on average, the cost to the government associated with each citizen would be exactly offset by the money that citizen pays in taxes.
In practice, though, the situation is often not neutral. In the case of continual state deficit budgets (e.g. the US for the past several decades), each taxpayer represents a net
cost to the state on average. I once read a line that was originally about retail, but it applies here:
"if you lose money on every sale, you're not going to make up the difference on volume." If every taxpayer costs the state money, more taxpayers will cost the state more money.
And this still ignores external costs that don't directly translate into monetary terms to the government itself, but are still within the area of responsibility of the state: as the population of a country, state or city increases, the cost of many things increases at a much greater rate than the population increase.
But setting aside all these problems with your argument, for a moment, let's assume that the purpose of state sanction of marriage is as you describe: to provide benefit to the state. If this is the case, then why would countries with runaway population have the same marriage policies as ones with negative population growth? If the objective is maximization of state revenue, why aren't the incentives of marriage tied to the anticipated income or tax revenue from the future citizens the state is supposedly promoting?
Relations that cannot produce new children therefore are outside the bounds of a state vested interest
There are plenty of vested interests of the state that have nothing to do with production of new children. Just because you feel that a relationship does not provide benefit in that specific area does not mean that they do not provide benefits in other areas in which the state has an interest.
