Bitcoin fixes a lot of things, but the idea that Bitcoin hashpower can somehow be an effective replacement for the utility of physical violence is patently absurd.
A free people must possess the means to do violence. A free nation must possess a strong military deterrent.
The deterrent must be comparable to the value of the resources they possess. The greater the value of the resources, the greater the incentive to seize control of the resources, therefore the greater the capacity to do violence in defense of those resources must be. This is true both on an individual level and on a national level.
Jason Lowery is a fucking idiot.
