"As a thought experiment, imagine there was a base metal as scarce as gold but with the following properties:

– boring grey in colour

– not a good conductor of electricity

– not particularly strong, but not ductile or easily malleable either

– not useful for any practical or ornamental purpose

and one special, magical property:

– can be transported over a zap on nostr

If it somehow acquired any value at all for whatever reason, then anyone wanting to transfer wealth over a long distance, instantly, for free, could buy some, zap it, and earn zaps on it."
