That would involve demolishing the insane, alchemical financial institution, ending the central banks, and restoring an actual monetary system. It wouldn't be with the best money (Bitcoin > Gold), but it would be a significant improvement.

That's totally unrealistic. It's like asking in 1943 "What would stop World War 2?" and we say "Well if Mustachio Man withdraws Germany's armies back to Germany, renounces his power, restores civil liberties, closes the camps..." 😂

Hypothetically though, we'd basically see a competition between Gold and Bitcoin at that point.
