It's kind of like paying your bills. If you don't make the payments they come take your car. Once he is out on his own he can respect their ideals or not and he can respect them or not. But as so many have already said as long as he is living in their house there are rules to follow. Once he is on his own he can do whatever he wants as long as he conforms to society's rules and laws.

There will always be rules to follow no matter where you are it's time to learn that now.

As for comparing home to a prison, you got to be kidding.
