It is relevant as to the misconception of wealth as a means to manage risk. The early communists got this wrong too with the notion of redistributing wealth, while what they really wanted to do was to redistribute risk.
As a risk management tool gold does a really poor job of this. Thus humanity as a whole has moved on. They might not really understand why quite yet. but Bitcoin, and cryptos in general are serving as a bit of an apocalypse for this understanding. And I think that it is actually starting to change the psychology regarding gold.
While I generally agree with the concept, I still don't see how it has much to do with using gold as an economic weapon.
No form of wealth is capable of risk management, because wealth has no capacity for thought. Whichever form of wealth is appropriate to counter financial risk at a given time is the one that will protect. All manner of financial instruments have had their day in the sun, and it is gold's turn once again. This is due to gold's broad acceptance and physical properties. Passive options, like gold, are usually the most effective.
Risk also has numerous forms. Gold does not apply to all of them, but it can assist depending on the circumstances - determining what's appropriate for which type of risk comes back to independent, rational thought.
It may help to define risk for the purposes of this discussion. I'm considering it to be any danger or negative outcome, financial or otherwise.
What's happening because of Bitcoin is indeed a shift in understanding, but I think it's more of a subtle realization by the masses that supply and demand of money are both malleable. The choice of crypto over all, including gold, is the simplification of that variability by making one element static (eventually). Historically, the closest analog societies have had to Bitcoin was gold. It's that simple.
On the point of redistributing risk, it seems that Wall Stret has done an expert job of it through manipulation of perceptions toward wealth. Maybe we should call bankers neo-communists?
