Never ignore the law of what's possible, amirite?
Possibility is the only limit placed on you by reality, it is the law you cannot break, the laws of man are reasons authorities use, rightly or wrongly, to exercise force against individuals or take their resources, to provide public infrastructure and services, to provide for the common defense... and share their spoils with their cohorts. It's easy to fall into the trap of believing such a system is omnipotent and eternal, but history shows us otherwise. It works until it doesn't work, because the law of possibility cannot be broken, and a system cannot violate it any more than an individual can. Idealism is nice, but you ignore the law of possibility at your peril.
