Because, unlike most businesses, Disney's park straddles two different counties (Orange and Osceola). Therefore, they have to deal with two different counties to get anything done in a consistent fashion. Further, by having control of their own infrastructure, they can control the standard of quality. Pass that to two different counties, and some of the differences between how the counties are managed will start to affect Disney's business. Image part of the park losing power due to one county deferring maintenance on their power grid, etc. Part of the "magic" of Disney is that they get to control the experience from road maintenance to providing power to the park. Now that control will move to the counties with no guarantee that they will continue to provide that infrastructure to the same standard as Disney currently does.
