Human nature is to find the easiest, fastest and most efficient way to do even simple tasks to make life less work. If people didn't look for the easy way out we would still be chucking spears at our meals and wearing animal hides on our loins. Beating a game with minimal effort is just what the majority of players do, they don't take the moral high-road and make things harder on themselves because they don't have that internal moral compass telling them that they'll get more satisfaction from doing it the "right way".
