I think the day of reckoning is to be a one shot deal, when the value of real estate or gold will not matter.
I've often wondered why gold is considered a safe have if currency fails. In an apocalyptic situation I would rather have a basement of canned goods, guns, ammo, camping gear, water purifiers, etc... Much better to barter with then gold. Why does gold hold so much value? What are the uses besides jewelry? I ask for my own personal knowledge, no agenda.
