Now obviously we can't compare this to fiats, but every other technical and crypto invention out there can be traced back (although sometimes with a bit of founder-discrepancy) to the inventor .. apart from this.
I rather put my faith in a technical or crypto invention that inherently doesn't NEED the ability to be traced back to anyone, in order to be able to trust it.
Suppose nobody would have ever heard of the famous Greek mathematician Pythagoras, and he published his mathematical proof for the a²+b²=c² rule anonymously. Would that make the proof, and thus the rule, any less trustworthy?
