Marriage is a thing created by governments. It is tax oppressive and obsolete.
I agree with your sentiment, but I would say government insinuated itself into marriage. At its best, marriage is a declaration of love and faith to each other and your community. I find the process of getting a marriage license from a county clerk in a poorly lit government basement decidedly unromantic and creepy.
But I got married anyway since it made my beloved happy. Three great years and counting.
Congratulations on finding a long term partner who agrees with you on this topic. I have no real regrets but it sounds like you succeeded where I failed, but I still got my girl!
