Keep in mind, a system of rules is just a system of rules. It takes someone to come along and knowingly look for "ah ha, gotcha" loopholes in a system to exploit for their own advantage.

It's completely possible to look at a system, realize there's a flaw, and not take advantage of it--perhaps even try to fix the flaw you discovered.

In the US, we're increasingly normalizing the culture of "well, it's legal" as to whether we should or shouldn't do something--the baseline of morales is becoming law.

Part of this is driven by competitive forces that put us at critical disadvantages if we don't follow suit. Taking the "high road" often costs more and hinders us to points we can't survive, so even if you don't want to play exploitative games on systems and people, in some cases, your very livelihood may actually depend on it.

"Don't hate the player, hate the game" comes to mind as players unwilling to come to a consensus that the game is flawed and adjust the rules so they can follow the intent of the game and not the flaws in the rules of the game.
