I used sarcasm to make the same point: life is not a Disney movie. Why was the bicycle, a very simple machine, invented 100 years after the steam engine, a very complex one? My theory: the idea of auto-motion had to be invented first. I imagine, the inventor of the bicycle must have observed a moving train and though: hey! like those levers, my legs could move a wheel as well. Eureka! The blockchain is a very, very powerful idea, the application as decentralized, untraceable currency is powerful as well, even though we clearly understand the pitfalls. But the idea is already there, with real life applications, with many advantages. For this particular case, I think we better fix/improve infosec rather than hunt down cryptos.
