That is one heck of a feeble and crumbling foundation for a legal doctrine. Secular marriage will collapse down to a mere at-will contract, voidable by either party at any time and for any reason or no particular reason at all.
It would be ironic that women, who benefit greatly from marriage (legally and otherwise) were suckered into supporting gay marriage because 'they should be allowed to visit each other in the hospital' and 'love is love' and it opened a Pandora's box that destroyed marriage as an institution.
Ironic but predictable that it would head this way. Sadly those predictions fell on deaf ears. And here we are.
We’re halfway there already.
Women can pull the rug out from under the guy with no notice.
He has to continue supplying cash, though.
Now consider if the tables were turned.
A guy could divorce a woman against her wishes and without notice.
She would have to continue providing sex whenever he wanted it or face the loss of professional licensure, or even imprisonment.
Would any woman ever consider getting married anymore under those conditions?
