I agree whole heartedly. Often wondered the same. But I'd always think a small amount of conflict is needed to keep our defenses evolving in case we ever come into contact with a society that would be more sophisticated than us in that regard. The same applies to computer viruses, pathogens, and even scams and haggling. I know at least some of these been explored already in fiction (Pandora's Star, War of the Worlds, Bender's Big Score).
