My point wasn't about bitcoin but about people posting their thoughts on bitcoin. If someone is going to try to get people rallied behind decentralized X, a good place to start is to offer practical reasons why that would be a better scenario than the status quo. Tell me why in the future I would want to take my retirement account out of my bank and deposit it into the decentralized ether. If I screw up that process, I lose my retirement account. Introduce a third party to help me with the process and you're on the road back to centralization. The same types of arguments can be made for other "this is serious business" use case for bitcoin.

Can the blockchain replace Twitter? Yeah maybe. But to compare overturning Twitter to overturning the NYSE shows a lack of proportionality and understanding of why things are the way they are in finance.
