First thing, the covert countermeasure will be undertaken when there are in orbit the first 100-500 tons of stuff. So don't think you can use those lasers or missiles to intercept the kinetic projectile. It will arrive and hit the "building yard" well before the first laser is operational.

Secondly, at some point or other espionage will reveal the project of placing up there cruise-missile-sized launchers and an advanced reactor that could easily be misused to breed weapons-grade fissile materials. With that, the corporation can expect a solid "terrorist attack" against the space station.

Really, now: the corporation, we're told, already indirectly controls the USA because it somehow has gained control of the US government. What else do they want in space or in Antarctica, and officially and openly in their name, too? That's the sort of arrogant greed that makes you lose what you already have.
