True, but we also live in a world of artificial scarcity. The people in charge of the resources are "lying" to the world about how difficult it is to make a product so that they can charge more. We can feed the world but we don't. We can shelter the homeless but we choose not to etc.
That said I am working on a program for Steem so I know what you mean when you say this platform needs to do more.
True. We can do a lot more goods in a lot cheaper ways. Even get to an abundance in many spheres. But it's not about money... or to be precise not only about money. Cos tokenisation and disruptive fintec will add to an (exponential) economic growth, but cant make it alone.
