No, you go to college to even be able to compete in todays job market since "college" is absolutely necessary in any professional field.
You can make plenty of money without a degree. What are your benefits to having a room? You can cuddle with doug because it'd be hard to do in the backseat of a car? Your tied down to one area, and it's much cheaper to sleep in your car. Thats money for booze, gear, gas, lift tickets you could use later in the season. Your whole opinion is skewed. Not everyone needs all of those little luxuries that you claim you need.
I don't want to get into people's personal lives and decisions but a great example of going to college and bumming it afterwards would be doug wouldn't it? College degree making shit money and living with a few room mates....
