"The root problem with conventional currency is all the trust that's required to make it work. The statement implies a lack of understanding of what currency is. Currency is inherently a social construct, and there is no 'avoiding it' because that's 'what it is'. We could try to avoid it by having for example very 'hard money'. We could just use Gold to back all currency. This wouldn't work in normal conditions, almost assuredly leading to deflationary spirals, but given that a total lack of monetary policy, and a 100% chance of a 'Black Swan' event, which happen every 10 years or so ... the first crisis would wipe out the economy. The 2008 crisis and COVID would have knocked all the dominos down. (Yes, there are good arguments that there would have been less risk in 2008 with better currency, but the conditions still remain). Of course, on the other end of the spectrum - you have 'abuse of monetary policy' which is bad, which is what Crypto would like to get rid of, but I'm afraid there's very little opportunity there. "It's time we had the same thing for money." No - this is a missatribution of the problem. For the same reason that BTC very quickly stopped being a currency and became 'kind of a store of value' (really just speculation), you can see the issue is not 'trust'. As people begin to speculate and as it increases in value, businesses cannot use it as a currency, and, people are likely to hoard it. So if we want a 'better currency' what we need is a 'better monetary policy'. Unfortunately, that part is fairly entrenched. Because currency is so intertwined with the nature of the economy, it's hard to separate. Alternatively - you could develop an 'easily tradable asset' that is backed by other assets, like property, but that would still require centralization. Or you could start your own economy, and use a kind of Seigneurage and export the currency, allow other nations to use it, but again, requires trust. BTC was a nice experiment but it's not going to work for reasons that are fairly predictable and obvious to people on the finance side of the fence.
