If there was a "super-centralized" network that already had major success (for example, imagine a world in which teletext or something was dominant before the internet) then the internet/web may have had a serious competitor. Instead, the internet was largely reverse-compatible with previous networks such as the phone network through dial-up.
Additionally, the latest wave of cryptocurrency hucksters have been selling their cryptocurrencies as a solution for a problem that cryptocurrency just does not solve. It is one thing to claim that they're wrong; it's another to claim that cryptocurrency has failed its original purpose entirely.
