China already has a ground based laser array for military purposes (blinding more or less permanently spy satellites). Some think it could be upgraded to hard killing satellites, which I don't think is yet possible (the amount of energy to burn a sat is also enough to ionise air and thus waste and disperse the laser's energy), but with something heavily constrained by heat dissipation like an orbital datacenter, that last array could overload it and fry it...

Yes because when your infrastructure is Earth based, your staff is Earth based and your customers are Earth based, your company's legal registration and owner are Earth based, it would be absolutely impossible for a government to enforce any type of jurisdictional control if your datacenters were in space.

And absolutely no one, anywhere, ever, has the capability to damage or destroy a satellite...
