Your comment cautioned against marriage for its "cost". Now you are talking about lifestyle preferences.
I’m just working back to first principals. You can be happy without the legal Russian Roulette of marriage is my overarching thesis, and I apologize again it took so many words to arrive at my point.
Just to add, here are a few other things that also limit your day to day freedom and add some risk of legal nightmares:
- operating a business
- owning a home or other building
- running for political office
- raising a child
- using a professional license (medical, law, civil engineer, etc)
