It's a curious thing, though. We have this idea that economic activity with consent is beneficial, and without consent it's theft and harmful. But this is a rule of thumb. The vast majority of things people do are - variously - pointless, inefficient, sentimental, superstitious, idle, crazy, and otherwise indefensible except by the reasoning that it's our right to do what we like with what we own, what we've earned and paid for. This we call wealth, and having it makes us feel happy and secure, but to actually centrally analyze it and assess its usefulness would be a bad thing. That would only make its value evaporate. We want to be free to do dumb things, and not to be told.
