It's completely nonsensical to take out hundreds of timeshare rooms, for years, in order to build a tower. Rooms, I might add, that hundreds of Saratoga owners have a legal, titled deed for, and also at a time when there are a ton of points still needing to be used and getting a DVC room is more difficult than ever. That line of thinking has zero basis in reality. What that poster proposes wouldn't get past any planning commission, not to mention a single lawyer, as it's a massive lawsuit waiting to happen.
Disney has enough of a headache with the gondolas needing to stop during a thunderstorm, or during periods of high winds, on the two existing lines. Extending that system only intensifies the headache, not to mention the logistics of a gondola line that runs to a place where parking is free. Could they charge for parking at the Springs? Sure. It's a good way to reduce the number of people visiting the Springs, though. Many locals aren't going to go if they have to pay for parking. Many guests with a car aren't going to go if they have to pay to park. Which means reduced revenue for the stores and shops. Which means higher turnover as places can't make enough to justify the cost of staying open and paying the Mouse. Which means... you get the picture.
The entire premise has more holes than a block of Swiss cheese.
