It doesn't stop but it has no legitimacy on established systems and institutions.
You're not realizing the importance of this: that the EXCHANGE takes place on infrastructure controlled by the establishment.
Its not in some dark alley where no one else but the individuals taking part are who are privy to the exchange.
And yes the model of crypto has existed as technology for decades, but when the double spend problem was solved, it became a logical advancement to then attach money exchanges to it.
In all of it's recent development as a money game all its done is mimic the legacy system, with exchanges as THE BANKS.
LIQUIDITY POOLS might seem like.. "POWER TO THE PEOPLE" but that's a falsehood because you still need on/off ramps if you want to utilize those holdings...
