Ecclesiastes 10:19 A feast is made for laughter, and wine maketh merry: but money answereth all things.
I remember asking a similar question once to my father about a £10 note for my Birthday when I was 11. The answer was something like. Father: "Well if you don't want it, I'll have it." Me: "No, just wondering what £10 is actually worth." Father: "Well I don't know, maybe some economist could tell you".
Contrasted to Bitcoin or fiat Currency, I believe the purpose is not to provide answers and is more speculative in nature.
Piano Teacher: If I pretended I could teach you a Beethoven's fifth, by Tuesday week I'd be telling a lie and I can't afford to do that. Not for financial reasons Mr. stickler but because of self-respect and that my boy is more valuable to me than 50 guineas a half-hour. I feel you should go now we got nothing more to discuss.
Mr Stickler: First class, never has anyone spoken like that to me for years, I like your style, I like the cut of your jib, integrity that's a valuable thing and I'm willing to pay for it. I'll Pay you 100 Guineas per half hour! Piano Teacher: That's more like it boyo! Now you'll find a black notes play, a bit louder than the white ones.
