The plot was hugely ironical: Timon and Roomba or whatever the warthog is named were building a resort in the jungle, and damning a stream to create a water feature. Simba showed up to demonstrate the error of their ways. The hilarity of any manifestation of the Disneyverse criticizing an artificial lake to build a resort goes without saying.
It does make sense. Disney wouldn't want anyone else to make their own resort.
The best part is the contrast between the two views on the Hoover Dam.
Here's a hint, the counter-point to preachy doom and gloom and damnnation of civilization: Bill Nye.
