Yes. You'd also learn relevant things from raising children and many aspects of the experience are even pleasant.

I don't think that there are no advantages to having kids and I don't judge people for thinking that getting children is a good use of there time.

As far as learning relevant things goes, a lot of the lessons of child rearing are learned by many people. Most of the time it's much easier to learn relevant things when you focus your attention on an area that isn't well explored by other people.

I do grant that having children means that you have experimental test subjects whose environment you can control very well. But that's not what most people mean when they advocate "raising children" and there are moral concerns.
