Both you guys are right -
However, I think it is important to understand
the degree and the speed of a dollar collapse would determine which placement is best. -

If the market completely melts down, it may be hard to liquidate the stock -

Another point worth noting is that, depending on the severity of the crisis, prices may rise rapidly -
When you discover, for instance, that a generator, wire, winch, spare Inverter, etc.. is a necessity under these changed conditions, the price and availability will rise directly proportional to how many people figured that out before you did, and the shopkeepers understanding of the increased value of the items.

Also, dealing in gold may be problematic -
By virtue of the act, and process of exchange you will stick out like a sore thumb when you have it and nobody else does.
It may be better to have had the item on hand - which directly relates to stealthy storage and theft protection - being separated from your stash by someones Big Brother -
of course which items are of most value to you, depends on the nature of the crisis — and on and on

Oh My
What to do?

Like always diversify, and build it up -
