I'm fine with recognizing partnerships in manners that could be beneficial to society, 2+ people residing in a residence can reduce resource consumption for buildings as well as reducing travel distance which ultimately makes for healthier living situations and less fuel consumption. So even if we get to renewable locally cultivated energy, the amount we need to use is reduced. That doesn't mean people can't live by themselves, or live in the middle nowhere on a 5-17 acre farm if they choose, but maintain infrastructure in small areas is just easier.
