Sorry just saw this. But "worth" is not calculated by money every time, no? E.g. we're not paying for oxygen while breathing but I wouldn't consider "weather costs $0 so it is worthless". But (continuing from the same example) if the weather is being hard to breathe due to pollution, I seek some action to fix this situation. That was what I am trying to find out, how could one enforce some payment out from this system, but can't see any workaround yet.
