I'm not going to argue about politicians and honestly.
There has been a change in Western central bank (and fiscal) policies since the Nixon Shock. Debasement has increased at unprecedented levels since 2008. From one crisis to another, they increase the supply of their currencies.
One way to signal that you're taking another approach, is to back the currency with something more tangible.
Habits and history are quite magical in the minds of voters, politicians, central bankers, investors and traders. But that's not my "end game" prediction.
I agree. One Big Question is whether digital money will be valued by fiat, or if there will be something backing it.
USD is backed by "full faith and credit" and GBP is backed by "I promise to pay the bearer". When pressed about _what_ these guarantees are, people answer "the economy". So Western economies could grow to the point that the inflated Dollars, Euros and Pounds come into line with what their respective economies can provide (e.g. export to foreign creditors who wish to redeem). Or those Western countries could actually practice the next part of the MMT approach they started and tax back the trillions (no, they're not really going to do that). Or they can just let the debts inflate away (this approach can spiral as it has in the past).
Some people might be more drawn to a currency that is (at least believed to be) backed by _something_. Of course, that currency will be digital as we're not really going to swap sheep stomachs for cobalt in the local market.
So, backpacker favours USD instruments and Western dividend stocks. JackAlabama favours actual Bitcoin. Some believe a switch to Renminbi is coming. Others, a BRICS SDR I believe that gold will likely play a part in the transition, based on the recent behaviours of some of the players involved.
In the end, we should be carrying digital representation of all sorts of things. Stocks, cobalt gold, oil, land, the right to dividends from solar farms, whatever. If so, gold is a likely gateway drug to non-fiat money.
Western countries have outlawed and restricted gold in the past, so I'm not saying that gold is safe to hold, just that it has a chance to play a part in the heterogenous currency environment once it becomes harder to value USD vs RMB.
