Not only does the college try to prevent us from making mistakes, it also it defines what mistakes are by setting these limitations. By being made to follow rules similar to those that parents enforce, students do not get to learn on their own what is right for them. The message is that we shouldn't be and can't be trusted. Furthermore, we don't need this protection from the school. Students have learning to do beyond academics and college is the perfect environment in which to do it.
College allows students to live away from home without being completely out in the world.
It is the perfect transition. At least, this is what college should be. En loco parentis prevents this gradual freedom. Parents are right to want to know who is teaching their children and what they are paying for. It is a benefit of a small school that parents can meet those responsible for their children's education.
