Schools are no different than corporations. They have acceptable use policies that you must follow. First of all, you don't own any of the equipment so your personal wishes are not a consideration. Second, the school is liable for your actions while you are using their equipment, thus, the acceptable use policy is in place to protect the interests of the school.
The tech dept reacted appropriately to your request. If what you want falls within the school's policy then they will help you out. If they do something that violates the policy because you feel that it is your right, the school and the tech department will be responsible. Get used to this model because when you eventually move on into the "real world" acceptable use policies may be even more restrictive than your school.
