Sadly there are many points I would have to disagree with. Your statement do not reflect a organized social group of human beings, but a free for all. You can by your own admissions recognize immoral behavior, but you have no moral character or moral fortitude and refuse to support moral behavior.
"What about the police shooting a fleeing suspect or shooting someone trespassing on your property? I would say both of those should be considered murder."
The fact is that it is not considered murder and yet you knowingly are in support of a system that has legalized murder. As a human being you get to believe whatever you want. I would however suggest to you that the fact that you will suffer the consequences of that support of murder is proof that you do not have a choice about being responsible.
That actually makes you a knowing accomplice to murder, which by the way in much of the western world is punishable by death. Thus the belief that it is OK to support murder is in direct contradiction with your knowledge that murder is wrong.
The above facts about what you have said is what makes below statement either a lie, or the statement of a very confused individual and at the very least morally ill person.
"I'm also not uncomfortable with my own statements. They line up perfectly with how I view the world, which is why I think the way I do."
There is no way a intelligent person cannot know that the above statements can only be from either a victim of Stockholmes syndrome or from someone who is morally depraved.
If you wish to live in a commune then sure, have at it. Pretty sure that's by and large an option to you. But a country wide removal of government would be a free for all. Millions of people can not organize themselves.
In my country, Canada, the police are not allowed to shoot people, shooting someone for trespassing is illegal, and the death penalty is completely abolished. My conscience is clear in that regard, but where my government has failed I support politicians that I trust to change the country for the better. I get the impression you don't trust any politician, but there are those with a record that I can get behind to represent me.
If you want your way of doing things, join or create a commune. En masse, new governments would ultimately form, many of them more oppressive than you experience now. You can't change human nature, and human nature consists of followers and leaders. Followers will always gather around a leader, making true anarchy unsustainable.
So if you want to damn some of your fellow man to actual slavery and death so that you don't have to pay taxes or adhere to laws, make no mistake that you lack any morals of value. I do not share your morals in that regard, and I feel the better man for it.
