When someone thing that something is unfair or not balanced, then they go cry for mommy. This is a fact that has existed in generations, even before humans wandered on earth.
To split it up a little, think a group with lions. These animals fight each other to see who is the strongest. They have no rules, and the one that runs away is the loser. The only different here, comparing to humans, is that the loser does not get any sympathy from other group members.
Nowadays those who was losers before is now leaders for whole countries or smaller states. Therefor they get the power to make laws of stuff they thought was unfair or unbalanced. As in war, if you use biological weapons, you will break a law. And due that some countries have signed on those laws, they have to act towards the rule breakers.
Games before were challenging, and when competing against other people came on the tape some people saw other do stuff that they couldn't do, and therefor they created laws against it so they don't have to learn the trick themselves. It is a challenge when something is balanced, but even a greater challenge to play against somebody that is better than you, even if he plays against the rules.
To sum up, humans are all in all individuals striving to have the best so others will give response to them, without putting so much effort in it. As long as it exist something called "mine" and "yours", people will always think something is unfair.
Thumbs up to you that understand where my point is going...
