I agree. Just having one mil resource while others have none can make you a winner, as your ships will attack and defend 39% beter FOR FREE. If GC would be a multiplayer game I'd be the first one to vote galactic resources out, because they unbalance the game so much. But it's a single-player game, so I can play how I want: restart, reload, cheat, or go down in flames. I never heard an AI complaining about that.

Absolutely... you need at least 2 military resources fully mined to go to head against the suicidal AI at the end game, and preferrably more. An AI mined military resource should be your very first target when war breaks out.
I like to 'stalk' military resources mined by others early in the game -- someone else gets one, I'll park a fleet of constructors within range and goad the other majors and minors into war with the owner and just wait for the base to be destroyed.
