Agency/Constraint hypocracy

Ok, so we all know agency is the power to act, and constraint limits actions and yadda yadda yadda. We all also know that most of these constraints and even the decisions themselves are a completely social construct. But does anyone else find it kind of strange that most of these "constraints" are things we put on ourselves? And then with agency we try to fight those constraints. Perfect example is lawyers. We form a country, set up a HUGE system of laws and rules, and then devout an entire field of study (along with several careers) to finding ways to bend those rules. In my opinion, thats a good example of the whole constraint/agency thing. But back to my beef with this whole thing. Why does humanity as a whole seem to enjoy creating order, rules, and constraints about as much as it enjoys tearing all of them down? I mean look at the mess in Iraq and the history behind it. We had peace after WWII...in a way. There were constraints against fighting Russia DIRECTLY, but nobody had any qualms with going into 3rd world countries, fucking everything up, and setting up a puppet government which will later bite us in the ass....or maybe we just support this guy named Osama back in the 80's and give him an assload of weaponry and then act surprised when he turns on us, I wasn't there at the time, I don't know what really happened, I'm just saying what I heard. But the point is that back then it's like we were making situations that would create more cause for agency, like we thought we were gonna get bored later on. In these days the agency is seen like this wonderful thing because action = progress (example: G.W. is the "DECIDER"), but in all honesty I would say constraint saves a hell of a lot more lives than agency. So to sum it up, humanity (not just society) creates all the constraints that limit their actions so that they create the agency they thrive off of so much. And that is my rant.
