The root problem with conventional currency is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.
I commonly hear that blockchain-based currencies can be a good replacement for fiat currencies. But current examples of blockchain-currencies are either company-sponsored or community-based. This again puts a big weight on a single actor. I'd rather trust the admin of money to a government than a company or a community of anonymous economists/technologists.
Finally, the ability go debase (I assume you mean devaluating) a currency is (arguably) a desirable characteristic. During crises, responsibly devaluating a currency can help a country's economy.
By what metric?

I'm skeptical that any benefit this brings outweighs the catastrophic damage it causes when misused. E.g. Weimar Germany, Zimbabwe.
