This is a great post @sndbox, and there's really very little I can say, aside from this being an excellent exploration of one of the challenges we face. The framework outlined here is a great representation of what's on offer.

The immediate thing that came to mind as I was reading is that this is very much a "top down" process. And it takes time.

Our most immediate piece of history for comparison is the Internet. At first, for a handful of hardcore developers and universities. Then for more general geeks... while everyone else thought it "creepy" and "a passing fad with limited applications." Then... "for nerds and the handful of people who could afford a computer." Everyone else? Skeptical and calling it a "scary place where pedophiles hang out." Then broader adoption as barriers to access come down-- price of connecting, price of computers decline.

There were fewer than one million global Internet users when I got my first connection in 1993... and everyone around me thought I was a freakazoid risking life and limb by connecting to "this internet thing." And it would be eight years before being online even reached 5% of the population.

My point here is that our possible "growing pains" are pretty similar to the Internet, itself. And right now? It's super early days... and we're at the "specialty niche for nerds and criminals" stage (in terms of public perception) and our job is to EDUCATE. And introduce cryptos to what I call "the next marginal user," the least skeptical person looking at what we're doing.
