All systems has cost so which one are you considering?
The current system has a lot of costs and drawbacks. Using the marriage as the norm has caused a lot of issue here in Sweden and the system is currently being tweaked every year to account for a changing culture. 1/3 of couples with children live as cohabitation rather than registered/marriage. Family law has to keep up. Same-sex families with children is an other area which is growing and the law has seen updated several times the last 10 years.
Rather than having laws getting tweaked and warped each year to account for a changing culture, maybe it is time to address it from a different perspective. If a child treat the adults around them as their parents, the adult treat the child as their child, and social environment around them treat the adults as the parents of the child, then why not also have the law treat them as the parents of the child? Outside of medicine does the DNA then really matter?
