I pretty much agree. Backed by fiat when fiat itself isn't stable is not ideal and which fiat would you even choose because they all suffer from inflation. Backed by gold could be interesting but I think in the end it has to be backed by an array of different stable assets. It can include precious metals, it can include fiat, it can include crypto derivatives, but it's not likely to be just one stable asset to rule them all because nothing is truly stable as anything has the risk of crashing.
