I would very much like to live off of the Earth.
There is no more a theoretical situation that US can have a country locked our of software or hardware so larger countries would not want to have this dependency or have NSA/CIA intercept your satellites before launch and backdoor them(that is their job will be the excuse).
LEO constellations require lots of launches.
This is not to say it’s impossible, just that for it to be within an order of magnitude of the cost on SpaceX, someone else needs to come up with reusability as well.
I have no doubt that someone will, I just wonder about when, and if it will be in time to benefit anyone else’s presently announced LEO internet access constellations. It’s also possible that Amazon will just eat the cost of disposable rocket launches; it’s not like they couldn’t afford it if they wished.
Do you honestly see China,Russia or India governments giving money to a foreign company when they have their own space programs? The governments to not min-max for short term financials and you also have on top of that the security issue to trust US.
Satcom isn’t an issue for governments right now. It is, however, for billions of normal people who live far from population/commerce centers.
I'd guess we'd have a few people trying to shoot them down from their back yard, actually.
