How about the "priests don't need to carry more than 500 gold" argument?
OK. Let me start:
Traders don't need troops.
Infils don't need bonds.
Lords don't need more than 500 CS of troops.
Rulers don't need to travel at the same speed as others.
Courtiers don't need estates.
etc, etc. I can go on like this forever. Whatever the question you are looking at, it remains a bad argument. I
don't care how much gold you think I need.
