What makes economic value?
Is it money? Nope. Money is the representation of economic value and is meant as a placeholder for actual economic value that you've created elsewhere.
So, then, is it work? It might be. Is your work valuable to someone else? Then, very likely it might make economic value. But different communities define value (noun) or value (verb) things differently. So, what might be economic value to one community (like cutting down a community tree) might not be value to another group.
So, then, who gets to decide? Well, YOU can. Make you're own currency and see how it gets traded relative to anothers, like.... say the USA!
