Good post, snap.
It's a tough subject... Government, society and the like. I generally like to draw comparisons between society and the human body. Within that context we could compare the conscious mind of the body to the government of society. I can and do on many occasions prioritize the enrichment of the conscious mind's experience over the enrichment of the body. I smoke, both weed and cigz, damaging my lungs or my body in order to appease the mind.
Anyways, stemming from this... We see the necessity of a collective homogeneity to the physical and social bodies. "Outside" material is criticized and undergoes a process of integration. If integration cannot be made then it is expelled (such as in the case of viruses). In this sense there is a forced conformity that encourages a relatively and isolated harmonious operation.
There's a tremendous amount of potential to be reached through this act of collective operation. The evidence can be seen in both the physical and social manifestations. Physical evolution can very well be seen in the light of a progression towards a platform capable of manifesting the "next level" in a sense. In this fashion we can see the history of numerous attempts at establishing a suitable platform and the attempts that have failed. Similarly, our societies go through a similar "survival of the fittest" progress. Currently, our western form of democracy is seen as the dominant force in our global environment.
There is the acknowledgment of the individual free will at play. There is and always will be the potential for one to elect to use violence, to use force. We deem this as unharmonious, as inconducive to the achievement of our collective goals. If we take a position where we will not use such methods in conflict resolution, one person exercising this ability would theoretically be able to rule the world. We again have historical evidence of appeasement being a risky gamble of a method. When gambling with lives a whole new level of consequence is opened up.
It would appear to be at this stage in our evolution to be a necessary evil to respond to violence with violence as it is in a way the be all end all of conflict resolution. You do have within your grasp the potential to remove a person from this corporeal arena effectively nullifying to a degree their consequence within it. It is tremendously difficult to work around.
