There's no more social stigma of living with your parents, and you should do so until you're ready to leave the nest with some kind of on the job training, an education or work experience and savings. I moved out when I finished college and looking back should have stayed longer to save quicker for a home, retirement, and get a head start.
If you have a good relationship with your parents, I would highly advise young people put up with mom and dad in exchange for free/cheap rent. There are worse roommates. You don't need to move out to spend tens of thousands of dollars to prove you're a "real man."
You'll be more of a real man when you have a house bought and paid for and no student loans or a trade in your thirties versus moving out at 18 or 22
