I mostly agree. Depends how far down Maslow's hierarchy we fall.

If we are talking about a complete breakdown of society, it's weapons, energy, and, food/water. Survival is king and always needed, so it's useful to always have this stuff on hand.

For a partial breakdown where survival is not at stake, say hyperinflation or other economic woes, precious metals and stores of value will be the order of the day. This is gold, silver, bitties, land, etc.

If we fall, we will always fall through the area where gold is useful. We may or may not get to the point where it's time to do gangster shit. Either way, having hoards of both on hand, and not going all in on one, is smart.
