Starship and access to orbit, as well as Starlink (which cheap access to orbit enabled) are indeed insanely powerful geopolitical tools. Many of the existing geopolitical engineers would hate to see him not be firmly subordinate to themselves.
I wouldn’t be surprised if the FAA’s decision is being used as a bargaining chip here. You don’t get to do things like this in the USA unless you play ball 100% with the existing people who control access to orbit.
Nobody is richer or more powerful than the people who presently control the satellite-based weapons and surveillance systems that the US operates. Nobody will be able to be in a position to replace or supplant them without some sort of negotiation with them.
Imagine it: with a working Starship, Musk could replace GPS, Keyhole, and whatever the rods-from-god system is codenamed, in a matter of months (or perhaps weeks, if the payload design work is already underway), for anyone on the Earth who he thinks would benefit his goals. A lot of the leverage that exists against him (and can presently be used to constrain him) would be gone, never to return. It’s already fairly obvious that the geopolitical status quo on Earth is not very important to him.
