yes, also bitcoin is not recognizable at a global scale (ask my mom, she has no idea).
I see only two problems with the gold+blockchain solution:
1. gold is mined at a 2% every year, meaning supply is not fix and it compounds to a devaluation of 50% in 34 years or so.
2. the oracle problem, how do we keep the peg between the gold vault and the blockchain? if someone steals a kg or the germans invade, the people of indonesia trade with an empty token.
I would say point 1 is weak, since technology makes everything cheaper but I still struggle with point 2.
let me know if you have thought about viable solutions
