I often wonder what the borg would do if governments decided to end 'marraige'.
So you have the ceremony but there is no need for the legal bit.
I kinda think things are headed that way because defacto and same sex relationships already have the same legal rights.
Marraige is open to abuse. eg. to get a green card or to get half the old guys money before he drops dead.
Now with so much focus on Gay people wanting the same rights as Heterosexual couples I half expect the government to drop the whole legal signing the marraige contract and everyone just have a commitment ceremony.
It would be funny to see them trying to draw the line as to when dubs could have sex and when couples could split up.
