Voyager is not traveling a relativistic speeds. We could definitely defend against someone sending voyager at us.

  That’s moving the goalposts. I said we could hit a planet at those distances not that we can create a relativistic impactor.

    No it isn’t since the whole topic here is that any civilization capable of accelerating an object to relativistic speeds and hitting a target from light years away is capable of defending against one. We can send voyager to target an object on the other side of the solar system but we are also perfectly able to defend against a potential voyager. Just because you now claim to not be addressing the actual goal at hand doesn’t mean I moved the goalpost; if anything you’re now implying you did.

      Voyager 1 isn’t a weapon so defending against it is kind of a meaningless argument. The Parker Soar probe is aiming for 0.064% the speed of light and covered in scientific instruments and shielding. So that’s arguably a solid baseline of what we could do in terms of speed. Even at those speeds we are still talking 8,000 years to the closest planet making it a poor weapon. Still, I doubt we could detect a barrage of incoming 0.0005c weapons designed for minimal levels of stealth in time to do anything about it.
