I think that Internet provision for the smooth and efficient functional performance of the blockchain network has been mastered to the heights where an individual can singlehandedly provide their own network without any reliance on big internet providers in the region.
Just like how starlinks made personal internet possible, so others have done and the fears of having to lose every Bitcoin or crypto currency to loss of Internet service at a very demanding time is quite bleak.
There may be some misunderstanding here, but you can't have your own internet if the global internet is down - nor can satellite internet function if there is no uplink from the surface of the earth to the satellites that transmit data. In other words, if someone were to destroy what is called the
Ground Station, all those satellites would become worthless.
