If that is true, then you can have an infinitely long war in which you gain loot by the following conditions being met:
1. Your enemy has no troops at all when the war starts (easily achieved, just truce-break before they have a chance to even start building any).
2. You have placed sufficient forces to cover, but not besiege, all of their provinces.
Provided these two conditions are met, the warscore will never change from 0%, and you will gain loot from all provinces. The question is, is what Fodoron said true?
Edit: This of course would not work if the enemy has any unfortified provinces with a thousand or more population.
