<Snipped quote by Etcetera>
I don't plan to. Quite the opposite, actually. See, I don't want anyone coming here to look for you. Not letting you return, no matter how we do it, would inevitably leave them to follow your trail here. And the intentions for our policies are, as you may have already guessed, meant to prevent that from happening.

Sounds to me like you have just from the way you've been speaking to me.

In the end, all that does is extend the trail others would follow. It doesn't prevent the trail from being created in the first place.
What if we travelled through time by some sort of light-related shenanigans to the end of this universe, escape through the dissolving edges of reality, and travelled back through time to our starting point outside of this universe?
