re: deflationary currency. Don't be mistaken, I'm not brushing aside the complexities of the issue. I do however claim that, current economical orthodoxy considers central bank guided inflationary currencies the de facto optimum. Agreed with that statement? Not that they're optimal, but that the vast majority of economists seem to consider fixed supply currencies broken beyond repair.
I agree that most economists consider inflationary currency optimal. I suppose, in a sense, that makes them the orthodoxy. "Orthodoxy" sounds a bit odd to me. In my mind the word is linked with religious orthodoxy--inflexibility, unwillingness to adapt, resistance to new ideas--"crusty."
Your usage makes Evolutionary biology today's orthodoxy, and Creationism ...what? More of a feelsy peeve than an objection.

Not to mention that, in terms of divisibility, until digital currencies came along, with decimal places that could be extended out, a deflationary currency wasn't practically implementable past a certain point. Physical currencies can only be split so much into smaller units, printed, and distributed, to maintain liquidity.
You know that old money is destroyed, and new printed/coined regularly, right?
Here's how we deal with divisibility in fiat:
For every dollar bill we destroy, we print 10 decidollars. For every penny we destroy, we mint 10 decicents(I know, but it sounds right:)). And sneak in a few extras because baker's dozen and inflation.
Problem solved!
