Yes , but the fact that we built societies on those things means there is great incentive for keeping it going (as even critics of capitalism eepeatedly keep noting).
The problem with cryprocurrencies is, that the one thing they are really not good at is being a practical, efficient replacement for fiat currency, which is why building societies on them is hard. You could as well speculate on the unique shape of certain types of sheashells and develope whole subsystems of people analyzing their shape, building seashell storage sacks and fake seashell prevention agency and it would be still be more efficient than crypto.
