look, people have different views on confiscation.
my view is: absolutely, it has happened before and will happen again. conversely, i respect others' opinions if they believe it is unlikely or impossible. make your own decisions and be happy with them.
but i'll end the topic with this: governments have been infiltrated by the biggest crime syndicate in all of human history. they lie to make wars for profit, and obviously murder millions and take resources for more profit. they violate laws and constitutions for their financial gain. they created fraudulent paper currency to fleece billions of people. they approve medicines which are known to be deadly just to make more profits and reduce the population. there is nothing they won't do to take away the assets of every human on the planet.
so what makes anyone think that gold is something special and is exempt from all that? if you look at the evidence, these same people have stolen and pawned all of the western gold reserves. the gold in the US fed actually belonged to the treasury and the US people (and other governments) so what right do they have to not audit that gold and return it to the rightful owners (e.g.: germany and the US citizens)? the west in in deep trouble with having little gold and they will DESPERATELY need to get as much as they can steal. XXX tons from libya, XXX tons form ukraine, canada, venezuela... etc. what happens when all the big stashes run out? they go after the smaller fish.
remember, they are criminals. you have what they want. it is highly possible or probable that they find some way to take what they want, be it legal or otherwise. criminals always persist until they are incarcerated or dead. beware of them.
