when they say "rules are made to be broken"...

...they are right, literally.

There are many reasons we make rules. One of them: we need order and certainty. Despite the practical benefits (from order & certainty) that we have long taken for granted, it's mainly a psychological need.

In practice, in reality, there are always smart people who can spot the opportunity to break rules and take advantage from it. They take calculated risks. How about those rule-abiding peope? I'll leave this to you.

In practice, in reality, we always encounter situations where rules look stupid. Really stupid. So we make exceptions, again and again, until breaking these rules seem so natural and inevitable...then we set new rules.

Yeah you get it, once new rules are set, the whole new circle runs again.
