It's no coincidence that some of the strongest criticism against cryptocurrency happens here, in a community mostly of banked, relatively prosperous people in stable countries. May you never personally experience being unbanked or otherwise financially oppressed.
Perhaps it's because the people on a tech forum see the problems of a tech hammer banging on everything it perceives as a nail better than others?
A better analogy - tech improves the hammer, it does not have to re-invent it. Example: open your phone and marvel at how easily you can send and receive funds from you banking app; 10+ years ago, you would have to go to a bank to do that.
