Everything is a tool. Some jobs can't be done with just any tool. Or more aptly for this metaphor, some tools are much harder to use for certain jobs than other tools. There's probably a way to back a screw out of a pressure treated 4x4 with a plunger, but i promise it'll take longer than using a drill. Look I'm not a programmer. Shit might as well be swedish to me. But i can't imagine a way to create auditability without creating some sort of transparency somewhere in a script. There's probably a way to do it. I'm not the guy to ask. But in the conversation of auditable script vs cryptography, i absolutely could see how each would serve its own unique purpose in something as dynamic as privacy centric digital money.
