Follow the rationale:
1. Nation states ultimately control three key infrastructure pieces required to run data centers (a) land (protected by sovereign armed forces) (b) internet / internet infra (c) electricity. If crypto ever became a legitimate threat, nation states could simply seize any one of or all these three and basically negate any use of crypto.
2. So, if you have data centers that no longer rely on power derived from a nation state, land controller by a nation state or connectivity provided by the nation state's cabling infra, then you can always access your currency and assets.

Whats less well known is as the Ionsphere heats up the upper atmosphere, it bulges out into space like a tyre sidewall bulge. This has the effect of putting an atmosphere in the path of LEO satellite, which then causes the LEO satellite to fall to earth because they are not designed to travel through an atmosphere.
Joule heating is the most important one which can alter the thermospheric dynamics quite significantly.[1]
