You can run your own hardware and pull in multiple power lines without establishing your own country.
I’ve ran my own hardware, maybe people have genuinely forgotten what it’s like, and granted, it takes preparation and planning and it’s harder than clicking “go” in a dashboard. But it’s not the same as establishing a country and source your own fuel and feed an army. This is absurd.
Fun related fact: My first employee's main office was in former electonics factory in Moscow's downtown powered by 2 thermal power stations (and no other alternatives), which have exact same maintenance schedule.
