Decentralized exchanges are a myth. Someone is creating the software and with the added complexity, lack of accountability with anonymous developers comes the risk of malware hidden in software updates.
The only reason I can imagine you or anyone would try to argue that the answer to an imperfect legal, regulatory, and financial system is to abolish it and move to a new system designed to bypass accountability and where the money supply was designed to be minted very rapidly to an anonymous group of oligarchs who then simply horde it, would be because there's a strong psychological motivation for you to attempt to convince other people to "buy" into your deregulated penny stock database not because there's any real world benefit over a regulated system, but because you simply want to sell your stock for a higher price - leaving the greater fools who buy database tokens holding a bag of something they can't use anywhere.
