>You can raid a data center if bad actors are utilizing it to break the law, but if some billionaire is using a moon relay to do bad stuff, the best you can do is de-allocate their bandwidth on the spectrum since you can't just hop over to the moon.

You don't need to raid the data center, you just need to compel the flesh-bound weakling in your jurisdiction that has effective control to cede the effective control. Or hack into it by obvious means.

> If any country chooses to facilitate this and allows this communication to be received, and propagates it to their internet, what does the rest of the world do?

If a hostile country wants to do that they don't need space data centers. Case in point starts with r and end with ussia.

Even if it is in space, somebody assigns the AS numbers and provides peering. You don't have to reach the other end of the rope to cut it.

As a worst-case scenario, you just stop Internetting altogether and only allow information to flow to and from AS that are in your geopolitically aligned jurisdiction.
