There are vast swathes of the USA where there are legislated monopoly players - they got that way by bribing the regulators.
In a number of other of parts of the world the monopolies are there for "Other reasons" - but they're all feeling the pinch of Skylink being competition they can't shut down - and the service is actually a sideline for El MuskOx anyway.
The REAL money is in providing low latency links between stock exchanges. These LEO birds could provide time-of-flight almost half that of submarine cables between London/NY and even better percentages on longer paths. (light in glass is slowed down by over 2/3) - and the FCC filings for the laser comms systems on Skylink make it clear that's what is being chased (ultrarapid dynamically reconfigurable laser pathing between birds across oceans - a laser tag version of OSPF)
If Skylink can be the first player into the ultra low-latency market, Musk stands to make _trillions_ out of it, and could pretty much GIVE away the comms service whilst still paying for his mars ambitions - or sell it at a price so low it would force the monopoly players to be honest and drive some revolutions in the marketplace
Some examples of gouging: New Zealand, 1990s - 2Mb across town: $2000/month - 1.5Mb from San Francisco to Auckland - $9000/month. From Auckland to 160 miles down the road: $27,000/month
The DSL pricing across middle America today is similar and will stay that way until there's competition. YES, fibre/cable is cheaper, but telcos don't charge what it costs, they charge WHAT THEY CAN GET AWAY WITH and if they can shut down all the competition, they can get away with a lot.
In other parts of the world, the barriers are firewalls for information, etc etc. 6 layers of IPv4 NAT and no IPv6 is a strong dissuader to look outside your borders, etc.
