... there is a bit more to it but it can just layers added on top of this basic confidence that it's worth something only because once it was *maybe* worth something physically (gold etc but now not)!

So now it's mostly insert between other things... or on top, or as a gate etc... but still confidence is main thing otherwise it could be sea shells / stones if really we were that confident in it (and of course money has the control in printing and remote devaluation so but overall I mean about confidence - we ASSUME somewhat based on what we see but if the other person would give you a piece of paper saying "THANKS" then on some level or even better because technically money is worth less than the face value because someone is still paying % for it / or gave it to someone else with %!)
