Except if not for RCID, most of those roads would likely have never been public roads. Disney would likely have continued to own the property which means Disney would have been paying property tax on the land they drive across as well as paying directly to maintain those roads, right along with the parking garages and they would not have been able to issue government bonds to help cover the construction costs, of any of that.
