Baikonur launch some of the biggest rockets ever made. Their equatorial disadvantage is kind of cancelled out by the fact their candles have very big motors, are extremely robust and well-proven. They can therefore launch big (or many) items into space reliably and efficiently.
We don’t have a launch platform, but then we don’t have much to launch natively, apart from non-existent GPS satellites. There’s no way we’ll be able to conjure up anything useful, commercially. It just seems like a really peculiar thing to invest in at that location. If we wanted a “domestic” launch site, somewhere like st helena would make loads more sense. ESA’s space port isn’t in France or Germany, or hung off the tip of Sicily, but in Kourou, Equatorial Guinea.
Lockheed (Rocket Lab) launch teeny weeny satellites from NZ, Florida and Alaska for very little cost.
