Just a random idea—one reason why starting your own country is difficult, is that land is scarce and everyone is fighting over it. So the obvious thing the dying-out countries should do is rent their land to charter cities. If your own population is not using that land anyway, why not rent it to someone else who will contribute to your pension funds?
(And more generally, here we arrive at Georgism again. The old are dying out, and some of the young are considering having children… but all the land belongs to the old, so the new children are born into debt.)
