I agree that they probably would have missed their chance to catch up with the frontier of your expansion.
Maybe an electromagnetic radiation-based assault could reach you if targeted (the speed of light is constant relative to you in a vacuum, even if you’re traveling in the same direction), although unlikely to get much of the frontier of your expansion, and there are plausibly effective defenses, too.
Do you also mean they wouldn’t be able to take most what you’ve passed through, though? Or it wouldn’t matter? If so, how would this be guaranteed (without any violation of the territory of sovereign states on Earth)? Exhaustive extraction in space? An advantage in armed space conflicts?
