For #1, I want increase in value over time, but don't care much about volatitlity or ease of exchange.
For #2, I want low volatility (both in value and it's first derivative).
For #3, I want low volatitlity in value and logistical ease of exchange.
So, for #1, I want a different thing than for #2 & #3, for which I might want the same thing, since the needs are, though not identical, at least overlapping.
Productive investments serve #1 well, so I’d leave it to them, and leave the design of money to balance #2 & #3.
I’m pretty sure I didn't invent anything, you just picked a random currency that meets neither your implicit goals not my explicit ones, because it's convenient for a pre-canned argument you wanted to make.
