It's interesting that this document states the ADULT individuals who are MARRIED have the right to found a family. So not even the UN believes people have a universal right to procreation at any age or under any circumstances.
My personal feelings are mixed. I'm not a fan of traditional marriage. It appears broken in the west at least. But, I think the initial idea, the one upheld in this document and in traditional civilization is valid. When people are in a position to support and care for children, yes, I believe they have a right to have them. Otherwise they do the children and society in general no favors by having them.
How many children should people be allowed to have? Should we have people like the Duggers taking fertility drugs to have 20 kids? What if a lot of people decided to do this? What if cloning became easy? What if someone decided to lab produce 10,000 children using sperm and eggs from a select group of doners? Do they have this right? The issue is complex and I don't know the answers. But I do see a lot of problems that result from wanton reproduction.
does such thing exists at all?
