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.
If there's one large orbital datacenter, then sure, ASAT is a threat to it. But if it's a dispersed swarm like the Starlink system?
Good luck making a dent in that. You'd run out of ASAT long before Musk runs out of Starlink.
