One of the problems faced by all the *-isms is that they often require a massively disruptive change to the way the world works to be implemented.
For the more cynically inclined among us, it is the rent-seeking aspect of the massive disruptions that tends to drive the "ism".
How much power and/or wealth does the disruption generate for those involved in initiating the "hope and change"?
I like the Jacob/Essau analogy to Steemit.
