I land here: it's probably not the best, most useful thing to spend electricity and compute on, but in order to compel people to spend it on what I consider to be optimal, you'd have to make me dictator, and there are a million other people who have equally strong and well reasoned opinions about where those resources should be spent, and if you're going to be fair about resource allocation, you inevitably end up with something that looks and works like a marketplace. None of them can ever be perfect, so you aim for reasonable and fair, and push for incremental improvements to the fairness over time. You gotta be realistic about least and lesser evils, and have gratitude and appreciation for the genuine good, and be extremely pragmatic about the measure and rate of progress. Things are pretty damn good - not utopian or optimal, but pretty damn good. And getting better, 3 steps forward, 2 steps back, consistently, decade over decade.
