Like the gold standard, a successful bitcoin would send our economy back into the dark ages. . . . Even if it became popular, governments would squash it because of #1 and because they like being in power. . . . With bitcoin, a single failure of the cryptosystem could result in an utter collapse of the entire financial network.
Negative feedback loops like this are basically homeostasis. In nature, positive feedback loops like exist with Bitcoin are lethal; the only thing that’s even kept Bitcoin alive this long is its novelty. Either it will remain a novelty forever or it will transition from novelty status to dead faster than you can blink.
