Impossible to raid ?

It's definitely much easier and much much cheaper to send a single rocket there blowing the assembled rather large target into still sizeable chucks of orbital debris than it is to deploy and assemble the thing there in the first place. And there are a few terrestrial actors rather capable of this. More than there are who could make it happen under whatever optimistic assumptions anyway.

In itself, a structure of this size in orbit is an efficient catcher of micrometeorites and orbital debris. Over "non-eternal" timeframes you don't even need a bad actor with good rockets.

Nevermind that in such a case, the eventual fate of these sizeable chunks of orbital debris is to become rods of god ... just without particular steerability.

It'd be a sight.
