I see this as a solution, not a problem
Don’t they have a 2-track marriage requirement in France and other euro states?
You can get married in a church but also must have a civil ceremony to register the marriage.
Give mammon his “license fee” for a civil ceremony and voila, you are married. No need to harangue and sue ministers and priests ( and imams - since there is no-homo marriage in the koran))
I wonder if this will open up the possibility of people getting sacramentally married and not bothering to involve the state at all.
