This argument might have made some sense in 2010 or 2011, when crypto was a new thing. But it's been over 12 years. Dropbox, iPhone, e-commerce were all successful products/business models in far fewer than 12 years after introduction. It's fine to express skepticism when a new technology gets immediately dismissed by people who may lack foresight. It's harder to sustain that when over a decade goes by and the "new thing" is still struggling to deliver on its promises.
