I was thinking of this today, like 4 hours ago. It'd be fun to make more similar experiments but it's hard to get users. I happen to have a big community but it's also hard to find free crypto tokens to distribute and see if they can get value. And even having users and tokens, it's hard to design a model that can create value for it. What I hadn't thought about is the reverse game theory model.
It's very useful to have that in mind, that one can think of exactly what behaviours to promote and then brainstorm what tools, restrictions and mechanics would encourage them. It's also fun to "theorycraft", but it's hard to find the means to actually put those theories into place.
I've always been a little passionate about Steem/Hive as an experiment that can be studied. It's recent, unique and has yielded interesting results. At the same time, there are countless theories floating around regarding what would be "ideal for humanity" or "ideal for a community", but as you said, people can't even agree on what moral goals should be pursued, even less on goals derived from them, and then an economic system derived from these goals.
It'll be really interesting to see in the future how these systems evolve and what little crypto creatures come out ahead in the Darwinian Evolution Centre, and then to see their effects on the global economy.
