The intent of the law was to promote families(I.E. people having children).

At the time the law was written, I'm sure they didn't consider that in the year 2007, we'd have widespread single parent households and that homosexuals would be demanding a complete re-write of our civil liberties laws.

So they wrote it to cover the people who would be most likely to be affected by it. Married couples.

Well, now gays are trying to re-write the marriage laws to include themselves. Fine. Whatever. But the law of unintended consequences means that all these things that were intended for heterosexual married couples will now be granted to a huge segment of the population for which they were NOT intended for.

You have two options:

Government recognizes gay marriage as "legal" and you do away with some laws that are pretty much hard coded into society. You then probably have to draft new laws (or not? please?) to reincorporate only that segment of the population to whom you intended to grant benefits to. (People raising families)

or

The path of least resistance, you tell gays that they can't get married.

The public has thus far chosen the latter.
