Golly, I guess I'd better be more selective with my verbiage. You may not be a statist, in fact, I really don't care what you label yourself. All I care about is whether or not what property you have, was actually acquired in a mutually consensual way. To be perfectly crystal clear, If what property you have acquired was not stolen or coerced from another man/woman, then I have no argument with you. If however, I make you aware that the property you have acquired (anywhere in the chain of custody) is of a questionable nature, as it were, obtained thru coersion or force, and you believe that that is okay, you would be gravely wrong.
Theft is theft is theft. Whether you give yourself some title of nobility, mantle of force, wear a costume indicating your prowess, what have you, it mattereth not. Governments are merely a coalition of like-minded associates who believe their solidarity is somehow superior to the rights of the common man. They are nothing more than a collective of superior forces acting as a unit. They have no greater right to steal from the many as the individual does another man. Duh comes to mind. It really is that simple.
Notwithstanding that, and the fact that it would be near impossible to determine whose property (ie. plundered thru the state) belonged to who (reasonably determinable), such that you couldn't return it to it's rightful owner, I suppose you could keep the plunder. Just remember, next time your government gives you a hand-out, it's likely to be ill-gotten goods. That ought to at least make you think twice about the justification of it all.
I personally think it's unfortunate that we participate in such activities, but what to do...?
