You do pretend to know, every time you say that RCID was approved for reasons other than EPCOT. Disney bought the land, showed the film, told the legislatures what their plan was to justify the charter, and you seem to believe that magically had nothing to do with their decision making.
What would you have it say? That they were ONLY giving Disney control of the special district in order to run an experimental government? That it was a science experiment?
Even Walt's EPCOT was always planned to be a tourist destination.
Of course it doesn't make sense, which is why RCID should have been disbanded long ago.
