What is your point?
money makes the world go round?
Just as there are an infinite number of ways to serve others, there is no limit on what could be considered money. Beauty is in the eye of the beholder and credibility is subjective. Without material proof, credibility is based on faith, and because this world is a physical illusion, we are saved
by faith alone.
Have you just read Adam Smith's wealth of nations and are trying to act smart? Or just entered "write something deep about currency" into chatgpt because that's how your post is coming across. This is a forum for discussion, right? Yet you've not really put any questions out there to discuss.
Anyone can call anything money, but that doesn't meant it will be universally accepted or trusted. Useful money is one that has a market, fluidity and a consensus of it's value in comparison to other currencies. You can trade any kind of commodity you like - oil, wheat, copper, but people distinguish it from currency because they do not conflate the two.
