I prefaced it with "Whether you like it or not", because what you think doesn't matter, you don't get to tell people what has value and what doesn't, the market decides and there's currently a market with billions of dollars in volume across many different exchanges that decides the value. You think it's a worthless tulip? Great, go and short it. I'm not sure what you mean by the 2nd paragraph, are you saying if all money was bitcoin, we'd only spend energy to secure that and we wouldn't do nothing else? That wouldn't make sense right? If all money was Bitcoin, there wouldn't be as much upside to it, because it will have already won, so you'd need to do other economic activities which will grow faster than that.
