> I fail to see how those aren't examples of how this technology benefits society.

Can you list examples of how it has helped society as a whole? Nothing you listed has anything to do with helping society. You've listed things you think are good things, but nothing is a society wide benefit. Building on top of Bitcoin or Etherium is great and all... But how does that help the average person? I've seen no trickle down or benefits from crypto that are anything but pure speculation akin to sports gambling.
