Therein lieth the rub, Twan. Humans are social creatures, and we tend to form alliances. These alliances take all sorts of forms, friendships, relationships, forums, etc.

The nations in Dom3 are fundamentally unsocial towards each other. If they weren't, then you could have a much more extensive trade-based economy and a diplomatic engine in the game-things that apparently are prevented from due to "the nature of the game"

Outlawing alliances would probably be the most powerful step that could be taken. I don't know how easily you could sniff out cheaters though-and monitoring everyone for cheating isn't really very fun, is it? and like Twan said, it's absurd to expect that particular "law" to be followed well by everyone.
