I believe to be one of the most pervasive misconceptions the notion that individual freedom is synonymous with or produces safety. Safety is subjective, no? Everyone has their own subjective fears which set their subjective foundations on which they construct a paradigm. Evolutionarily, I personally believe we are still far from being advanced enough as a specie to live in absolute peace. So, it's not without risk that we take on the responsibility of self-sufficiency and a personal safety - which in my opinion are the same. Getting somewhat off-topic.
We already have a private military confronting us. There are several existing in many nation-states. MIlitarized police, TSA, DHS, DEA, ATF etc, and military weapons producers such as Lockheed Martin, Boeing, Raytheon, etc. All of these entities necessarily depend on syphoning wealth from the populace in the form of taxation in order to fund their agendas.
Over the past two hundred or so years the world has seen a rapid and exponential increase in the police state. It is indisputable in my opinion. From political prisoners to the hundreds of millions of innocents mass-murdered in the past century alone, in order to economically cripple "non-allied" nations, by military forces. Supporting the view that this taxation based funding is necessary.
I would rather face small arms than air-strikes, missiles, and even nukes.
Just my quick 2¢ while i have a sec!
