School bodies expand and contract over time as the demographic makeup of a district and school changes. "Limited capacity" isn't strictly true.
School sizes do change over long time horizons as demographics grow. This is true.
But school buildings have limited capacity and teacher:student ratios should be maintained. These cannot be changed instantly. Planning happens according to people actually living there, so if a lot of people are circumventing the rules and cheating their way in it breaks the system.
