Simply put: times have changed. With the rising cost of living (food, shelter, transportation) the thought of home ownership is feeling out of reach financially for a lot of people, which is why it may be advantageous to stick around home for a few more years to save that extra money.
If you can put up with the idiosyncrasies of living at home, then why not take advantage of the opportunity? Free meals and someone doing your laundry are major benefits that often get overlooked, but you want to make sure you're actually making financial headway in order to maximize the time you are spending under the same roof as your parents. If you're spending as much (or more) money than if you had your own place, it may not make sense for you.
Aside from the monetary benefit, there's also the emotional support of carving your path in life. There's also the fact that your parents aren't going to be around forever. You may as well enjoy as much time with them as you can while they are still around. If it's a suitable arrangement, then why not?
