This quite shallow rationalisation. If you live in big city and have more prospects on finding someone else, if your life is all rosy and beautiful you might not have big desire to stay committed to rest of your life or more than couple months. All this ends when you or someone close to you gets sick, you lose your job or money. When you have to support your parents or siblings your dating pool shrinks quite a lot because you do not have time/money to spend on new dates. Your health is not going to be perfect all the time, you might get hit by a bus any time. It is more of insurance policy which you give and receive at the same time.
So again if you live in big city and break your back or whatever, it is far easier to get any help. Think of all those living in some far from anywhere places. People who have to stick together to afford house. Those things create "social norms" and not the other way around. You might be angry at aunts pushing social norms on people without thinking, but they did not invented those norms.
