Yeah, unless you're the Toughs, of course. In the current case, the UNS may have their own TAD up over the top of the Tough's TAD. We know the UNS's TAD goes further out. Since the Toughs didn't allow the UNS to teraport into the Tough's TAD, so I doubt the UNS will give the Toughs their codes.

It seems to me that if the ancient balloons wanted to terraport gravel into the can of sky, they would have just terraported the gravel directly without bothering with the World Mover ships. I don't know if we will ever get an in-story reason for why they didn't.
