So whether the government is robbing you depends on whether they have a legal claim on the money they are taking. Simply taking it by force is not enough.
I don't expect you to agree with me now, but is it any clearer where I am coming from?
From a personal perspective, the more of that expropriated property that is misappropriated by government for all kinds of corrupt and inappropriate purposes, the closer I am drawn to pure-anarchist thinking. Years ago, I would never have imagined considering anarchy potentially a
good thing.
If I could somehow allocate my taxes to certain areas and exclude others (army, corn and other farming subsidies) I would feel better about paying them.
