Ultimately, there is ONLY ONE thing in the world of real value. Everything else is just based on perceived value. That ONE thing is the human labour.
You're right to an extent but how do you safely store that value on an efficient way? Gold and silver is safe but not efficient. Fiat isnt safe but is efficient.
Neither of those allow you to secure your wealth without 3rd party involvement when making international purchases. Someone can also always fudge the numbers.
Crypto changes the whole game.
