and while I'm nitpicking, we can "take it to the good times"? what?

What's up with that Starship song that goes:

So if the world runs out of lovers
We'll still have each other
Nothing gonna stop us now.

Is the singer saying "If everyone else pairs off and there's no one left to date, we'll be smug because we snagged somoene early on? Or is he saying "If everyone who is in love is magically vaporized from the earth, we'll still be together and we will have somehow been mysteriously exempt?" Or is he saying "If everyone else becomes so tired and cynical that they stop loving anyone at all, we'll still be going strong, which is cool, except our friends will be really depressed and probably hate us for it?" Or is he saying -- nevermind, this is exhausting. Fuck it.
