I meant to say "I'd recommend video and notarized statements", and the time frame for editing has passed. Obviously you always have witnesses, per canon law.
And when I said "more important than the spiritual or moral reasons", that was a clumsy turn of phrase. The idea I was trying to get across was, while a couple can always say "we're impeded for the moment from marrying, but we shall not sin, if we are that big of a temptation to one another, we'll spend our time together in public, or in the company of others, and make it a point not to be alone behind closed doors, until we can get married", the law and the government couldn't care less about your intentions --- they need to see a marriage license with ink and a certified time and date stamp on it, before you can file your taxes as a married couple, get on the spouse's good insurance, and so on.
