There are many forms of family(and family-like) units that are not given the same benefits as a government-recognized "marriage".
- Adult children living with their single parent.
- Adult siblings living together.
- Best friends living together.
- etc.
These family and family-like units provide stability to society and should qualify (if they wish) for the same benefits given to "marriages".
So instead of a narrow benefit given only to "marriages", the government benefits should be expanded to any family or family-like units that would benefit from the same governmental status as marriages.
