government encouraged (w/incentives taxes, etc.) people towards marriage because it was good for family life, thus good for the country, but this is also an incentive, a nudge, in the wrong direction.
if people want to be together, what's the drawback to NOT having a marriage certificate, certified by the justice of the peace? if love is true, none of this will matter. we can make up our own contracts. we often make up our own vows, do we not?
