The answer is actually quite simple. If you're strongly for living on campus, even against your parents' wishes, then as an adult entering the real world and post-secondary education you need to be man/woman enough to support yourself mentally and financially. Tell your parents that you need to grow up and learn how to handle yourself independently, at least for the first year of university (as you can always transfer schools/programs afterward). Tell them about the unique opportunities that your program may offer (though this one is hard to pull off as undergrad is the same almost everywhere). But, really, it comes down to finances. If you want to live on your own then be prepared to take out student loans and not depend on your parents to financially support you anymore. I strongly believe that going against my parents' wishes, taking out student loans, and moving away from home really impacted my growth and maturity as a person. Five years later, I'm now in professional school and have earned the respect and admiration of my parents for doing that and succeeding along the way. Some people may gain this sort of independence and world knowledge even while living at home, but chances are that if you're on this forum then you're not the typical high schooler with full freedom to do whatever you want from your parents. This is especially important for students who are sheltered, who have a high dependency on their parents, who have a large family and cannot study at home, who face mental, physical, and emotional abuse at home, and so on. Everyone's reasons are different. Figure out what yours are and act on it. You're now becoming a full-fledged adult and nobody can keep you locked up in the house or force you to stay at home. Those that do, didn't really want to move away from home and leave the financial security of their parents.
