Eh, I'm taking my carrier to the bubble temporarily for cheaper transfer of the entirety of my ships and modules to it anyway (comes in at about 1/8 of the cost of having them delivered to Colonia and in half the time), so bringing back a cargo bay full of tritium with me just makes sense.
The hypothetical was merely to expand upon that, creating and then parking a dozen extra accounts (each using a ship with ~800 cargo capacity full of tritium) on the carrier would mean that once I got there I could maintain stock for personal use, like keeping enough for a return trip, as well as provide other players stuck here with more than the carrier itself would be able to haul.
