With money, most anything is possible. However, it does hurt the bottom line. Limestone and sink holes in Florida have thwarted many things. Knowing how suitable the land is for development, is important. Wetlands are also an important development hurdle, and the map shows a few ponds etc.
If both parties participate in friendly competition then you are absolutely right that the consumer is the ultimate winner. In the end it doesn't matter what prompts improvements only that they are done and done right.
I don't think the competition is simply going to be about adding attractions. I think Universals land purchase signals the desire to become a destination which could be more that just a day or two loss for Disney that may not be received well. They really have never had someone try this before and since they are kind of in bed with each other due to location and the Marvel licensing piece they both could try to make this misserable for each other. Business don't really like competition because it's only good for the consumer.
Not at the moment. Right now it appears to be tit for tat which is fine and good for consumers. Unfriendly starts when they one tries to block construction efforts of the other or they decide to nitpick a contract. The really is no reason for either to do that but strange things happen when the status quo moves.
