It is not impossible, impractical, or immoral to overthrow the government.
The ideas of what a free society is, or ought to be, are pretty well established. Surely, there will need to be a great deal of outreach for more people to understand those ideas before they take hold, but the questions of defense, roads, economy, and law, have been answered. The question which remains, is how to achieve this.
Not that people haven’t tried to answer it. The general public’s rightful aversion to violence being taken into account, all proposed paths which have gained any sort of traction have attempted to portray themselves as peaceful. The democratic process, civil disobedience, peaceful parenting, and education, to name a few. This all sounds very positive, until we realize that these methods are not peaceful, they just predetermine who the victims of the violence will be.
While we vote, disobey, breed, and teach, the State robs, kidnaps, and murders. (Need I mention that the State is also voting, disobeying, breeding, and teaching?) With every moment that this is allowed to continue, the violence gets worse. With modern weaponry being what it is, nuclear, biological, and chemical weapons, it is not beyond the realm of possibility that the next outbreak of State violence could result in the extinction of the human race. Hell, it wouldn’t even have to be war, some intern in a biological weapons lab drops a petri dish, doesn’t tell his supervisor, and the next thing you know some weaponized virus is turning us into Resident Evil. That’s right, not the slow biters of The Walking Dead, but the strong, fast, variety of zombie that isn’t stopped by a locked door.
Science fiction humor aside, this is very serious. We all spend a great deal of time talking about freedom, and economics, but the very harsh reality of this struggle is that the survival of our species is not guaranteed, and the greatest threat to it is very plain to see. Mankind may well know extinction, before he knows peace, and it is entirely possible that we are already too late.
