I don't think the "warlord" and "district manager" roles are particularly mutually exclusive, you know. Even Germanic war-chiefs could hardly be on the warpath *all* the time for entirely practical reasons already, and unless I'm mistaken their status came in no small part from being wealthy enough to equip and maintain their own "household" warriors (ie. the soldiers of the BG unit) they could take to the field with on a short notice...
Romantic fancy aside, that translates to owning and managing property.
