I suggest you think before you speak. In a libertarian society, there is no law that requires one to keep a firearm, nor is there a mandatory period in which an individual goes through training in the military. If there is no law to keep a firearm, then there is no cause for one such as yourself to dream that in your fabled libertarian society, all would choose to keep a firearm. Nor is there any reason for one such as yourself to fantasize that in fabled libertarian society, all would receive the training that one gets when enrolled in the military.
Remember, in your fantasies, your libertarian society is not Switzerland.
Think before you speak.
Have you already forgotten that
you described a hypothetical situation* where "everyone chooses to have a weapon," and
you concluded that "then the number of injuries due to accidents, twitchy fingers and rage would likely rise." And I responded by showing that in Switzerland "all able-bodied male citizens keep fully automatic firearms at home" and virtually no one dies "due to accidents, twitchy fingers and rage."
Military training is irrelevant to "the number of injuries due to accidents, twitchy fingers and rage" otherwise these events would be common in gun owning populations in countries without mandatory military training. Which they are
NOT <--- (I guess my mistake was to assume that this is OBVIOUS, unless of course you were
thinking)
* - Are these not your words? Is it not
you who speaks of a scenario where everyone owns a weapon?
2. If, contrary to point 1 above, everyone chooses to have a weapon, then the number of injuries due to accidents, twitchy fingers and rage would likely rise.
