Getting the rocket boosters out of the jungle, back to the seacoast (barge to Cape Canaveral or West Coast US? Getting satellites and boosters and upper stages to/from Ecuador at what port? Through Panama Canal takes a bit longer, costs canal fees of several hundred thousands dollars for the ship.
I don’t think SpaceX would be interested until the BFR rocket is operational. It could fly to any spaceport in the world.
