There is no point to cryptocurrency beyond the mechanics of the technology that powers it, and the constraints imposed by it. To ascribe some nobler point or ideal—which is impossible to coerce through the technology alone—is to naively expect something from cryptocurrency that you will never get.

If you want a currency technology and platform that constrains activities to morally benevolent activities, it must either be heavily regulated (traditional systems) or designed and implemented as such (no such system yet exists).
