Are CSU colleges even worth dorming at?

Here's the thing, my parents are going to pay for my college edu. and so they want me to go to Fresno State (a college really close by) and commute. However, I want experience college in a dorm and away from home, but dorming is much more expensive. Do you think it's illogical(or exhorbitant) to go to another CSU and dorm even though there is CSU close where I live?
