Desert land is free. Floating data centres in the middle of the pacific is free.
If a state, or even rich billionaire, wanted to take out your data centre in low earth orbit, it's only a few million dollars to launch a retrograde rocket which explodes into 10 ton of shrapnel, or even less to forget the orbit and just launch it directly up.
You can do the same to the ones in the Pacific and desert too.
It's a declaration of war much the same.
