i'm not sure why expanding temples can't be done with global treasury.. sure... it would mean priests or whoever don't have to carry a load of gold from 1 side (rich followers) of the continent to another (poor, just starting up) to build it up.
errr... why not? That exactly is the idea. The local carpenters, bricklayers and other workers won't exactly accept an "I have that gold three realms away somewhere".
