Are you referring to buying land from a country? That's a form of cession, and it's certainly not unprecedented (see: Louisiana Purchase). In my eyes, it's the moral way to go about acquiring land, with the alternatives being annexation and conquest.

Under what conditions are you okay with territorial control changing hands? Can land only be sold to other existing governments?
